  • Non Doppler-tolerant pulse compression in radar systems
    Patent number: 9041598
    Abstract: A method for processing return radar waveforms in response to transmitted radar waveforms. The method includes receiving, with a processor, a return radar waveform having a Doppler shift larger than Doppler tolerance. The method also includes separating, with the processor, the return radar waveform into a plurality of shortened waveforms. The method also includes compressing, with the processor, each of the plurality of shortened waveforms with a shortened form of the return radar waveform. The method also includes 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.
