Patent ID: 7646326

Claim:
An apparatus for producing simultaneous synthetic aperture radar and moving target indication, comprising: a plurality of waveform generators each producing as an output an independent radio frequency signal so as to produce a plurality of independent radio frequency signals; wherein each of said plurality of waveform generators being independently controllable in frequency and phase; a transmit/receive module having a plurality of inputs and outputs, and a channel disposed between each corresponding pair of said plurality of inputs and outputs; wherein each of said plurality of inputs of said transmit/receive module being connected to the corresponding output of each said plurality of waveform generators, and wherein said transmit/receive module further comprises means for: modulating the amplitude and phase characteristics of at least one of said plurality of radio frequency signals transiting in either direction therethrough; modulating any of said characteristics independently of any of said other characteristics; and modulating any of said characteristics of any of said plurality of radio frequency signals independently of any other of said plurality of radio frequency signals; a waveform control subsystem having means for applying signals to: any of said plurality of waveform generators so as to control the frequency and phase of said radio frequency signal output therefrom; and any of said disposed channels of said transmit/receive module so as to control said means for modulating said amplitude and phase characteristics; at least one radio frequency radiating/receiving element being connected to at least one of said transmit/receive module outputs for radiating radio frequency signals into free space, and receiving from free space radio frequency signals reflected from targets; and a signal and data processor for extracting synthetic aperture image data and moving target indication data from received radio frequency signals.
