Abstract:
1. A method for processing return radar waveforms in response to transmitted radar waveforms, comprising: receiving, with a processor, a return radar waveform having a Doppler shift larger than Doppler tolerance; separating, with the processor, the return radar waveform into a plurality of shortened waveforms, wherein a size of each of the plurality of shortened waveforms enables an assumption that a linear phase across a subject shortened waveform is constant; compressing, with the processor, each of the plurality of shortened waveforms with a shortened form of the return radar waveform; summing, with the processor, the plurality of compressed, shortened waveforms by computing a Doppler Fourier transform for each radar range bin of the return radar waveform using the plurality of compressed, shortened waveforms; and using the summed shortened waveforms for at least one of: target identification, target detection, and target tracking.
