Digital Coherent Radar

View page
US Patent:
6339394, Jan 15, 2002
Filed:
Sep 15, 2000
Appl. No.:
09/663136
Inventors:
Ben H. Cantrell - Springfield VA
Assignee:
The United States of America as represented by the Secretary of the Navy - Washington DC
International Classification:
G01S 1300
US Classification:
342159, 342 82, 342134, 342175, 342195, 342202
Abstract:
The digital coherent radar generates its transmitted waveform from a low intermediate frequency (IF) and a local oscillator (LO) by digitally generated waveforms after passing through digital-to-analog (D/A) converters. The LO is increased in frequency using a product multiplier. The IF representation of the transmitted waveform is upconverted using the LO. The transmitted waveform is amplified and passed through a circulator to an antenna. The echos are received through the antenna and passed through the circulator and receiver protector. The received signal is then downconverted to a digital signal and passed on to a processor. Finally, the waveform is reset and restarted by the local oscillator generator, the digital-to-analog converters, and the analog-to-digital converter at the beginning of each pulse. It must be insured that all pulses in a pulse train are identical even though there are deterministic errors in the representation of the transmitted signals desired coherent component. This insures that all transmitted and received signals regardless of their errors in representation (i. e.

System For Simultaneously Transmitting Multiple Signals Through Each Element Of A Radar Array

View page
US Patent:
7623063, Nov 24, 2009
Filed:
Sep 5, 2007
Appl. No.:
11/850065
Inventors:
Ben Cantrell - Springfield VA, US
Ching Tai-Lin - Burke VA, US
Assignee:
The United States of America as represented by the Secretary of the Navy - Washington DC
International Classification:
G01S 13/00
US Classification:
342175, 342 13, 342 25 R
Abstract:
In conventional phased array antennas, multiple signals that perform different functions, such as radar, electronic warfare (EW) and telecommunications, can each be simultaneously transmitted only through a different sub-aperture of the array. For maximum power and efficiency in conventional phased array antennas, the power amplifiers operate on one signal at a time. The present invention forms a common waveform from multiple signals for transmission through a common aperture of a phased array antenna. In wideband operations, waveform-shaping and amplitude-to-phase-modulation are used to transmit high-power diverse waveforms through every element of the array.

Simultaneous Transmission Of Multiple Signals Through A Common Shared Aperture

View page
US Patent:
20050024262, Feb 3, 2005
Filed:
Aug 2, 2004
Appl. No.:
10/911537
Inventors:
Ben Cantrell - Springfield VA, US
Ching-Tai Lin - Burke VA, US
International Classification:
G01S007/28
US Classification:
342175000, 342194000, 342192000
Abstract:
In phased array antennas, multiple signals that perform different functions, such as radar, electronic warfare (EW) and telecommunications, can each be simultaneously transmitted only through a different sub-aperture of the array. For maximum power and efficiency, the power amplifiers operate on one signal at a time. This patent provides the technique of forming a common waveform from multiple signals for transmission through a common aperture. To practically implement this technique in wideband operations, processes performing the required waveform-shaping and amplitude-to-phase-modulation are devised that can transmit the high-power diverse waveforms without serious intermodulations and spectral distortion through every element of the array.

High-Speed Digital Pulse Compressor

View page
US Patent:
42374618, Dec 2, 1980
Filed:
Feb 15, 1979
Appl. No.:
6/012409
Inventors:
Ben H. Cantrell - Springfield VA
Bernard L. Lewis - Oxon Hill MD
Assignee:
The United States of America as represented by the Secretary of the Navy - Washington DC
International Classification:
G01S 1328
US Classification:
343 5FT
Abstract:
A pulse expansion and compression system, especially useful for radar ranging, comprising a pulse coder for expanding an input pulse and a pulse compressor of the matched-filter type. The coder consists of a plurality of delay stages into which the input pulse is fed, a discrete Fourier transform (DFT) circuit to which the output signals of the delay stages are fed, a time-dispersionmeans (TDM) comprising an arrangement of delay stages for differently delaying the output signals from the DFT, and a coherent summer for adding the real and imaginary parts of the signals from the TDM. The summer output is fed to a phase modulator and then to the transmitter. The echo signals are conjugated, time-inverted, and passed through the same DFT as the input pulse signal. The outputs of the DFT are then passed through a TDM of the same type as the first TDM, but this time in time-inverted order. The outputs of the second TDM are fed through a coherent summer and an envelope detector to provide a cross-correlated facsimile of the original input pulse.

Fast Scan Multimode Radar

View page
US Patent:
39493962, Apr 6, 1976
Filed:
Feb 25, 1975
Appl. No.:
5/552895
Inventors:
Ben H. Cantrell - Oxon Hill MD
Assignee:
The United States of America as represented by the Secretary of the Navy - Washington DC
International Classification:
G01S 902
US Classification:
343 5R
Abstract:
A new system and technique for providing multi-mode radar operation from a ingle scanning radar antenna at conventional scan rates. A single radar antenna has a plurality of feeds forming individual main-lobe beams equal in number to the number of radar modes to be utilized. Each of the beams is separated in azimuth by a fixed angle. theta. , and rotate together at the scan rate of the antenna. For each angle. theta. that the antenna rotates the radar mode is changed so that the antenna feeds are cyclically multiplexed to each of the radar modes desired.

Method And Means For Short Pulse Interference Rejection

View page
US Patent:
55024483, Mar 26, 1996
Filed:
Aug 30, 1977
Appl. No.:
5/329695
Inventors:
Ben H. Cantrell - Oxon Hill MD
Bernard L. Lewis - Oxon Hill MD
Assignee:
The United States of America as represented by the Secretary of the Navy - Washington DC
International Classification:
G01S 316
G01S 328
US Classification:
342381
Abstract:
A radar interference circuit which rejects both continuous noise and shorulse interference signals. A plurality of omni-directional antennas are placed around the main directional radar antenna and connected in differing sets to a plurality of canceller means to each of which the main antenna signal is also connected. The canceller means for each set of three Omnis and the main antenna cancels out the white-noise interference received by that group of antennas. The outputs of the plurality of canceller means are then taken in different sets of two each, subtracted and compared to a threshold signal. If one or more comparator outputs are above the threshold, signifying that the antenna pulse signal is being received through the sidelobes of the antenna patterns, the outputs of these comparators will be a one signal and the OR gate, to which the comparator outputs are fed, will provide an output to blank the radar. Thus, short-pulse signals arriving through the sidelobes of the antenna patterns are rejected as interference signals.

Frequency-Coded Monopulse Mti

View page
US Patent:
53472810, Sep 13, 1994
Filed:
Jul 23, 1976
Appl. No.:
5/707465
Inventors:
Bernard L. Lewis - Oxon Hill MD
Ben H. Cantrell - Springfield VA
Assignee:
The United States of America as represented by the Secretary of the Navy - Washington DC
International Classification:
G01S 1352
G01S 1358
US Classification:
342160
Abstract:
A pulse-compression, MTI, doppler-radar system for determining target velty information from a single, frequency-coded uncompressed target-return pulse includes a coded modulator, two pulse compressors, and a phase-comparison processor. The coded modulator generates for transmission an uncompressed pulse with the first and second halves of the pulse coded with the even and odd harmonic sidebands of a pulse repetition frequency, respectively. The first and second halves of the pulse returning from the target are pulse compressed simultaneously by the two pulse compressors. The phase comparison processor then determines the phase difference between the compressed pulses to obtain the target velocity information.
