Abstract:
1. 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 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 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 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.
