abstract

  • In this paper, a novel approach for concurrent extraction of target range and Doppler information in radar systems is introduced. A pair of orthogonal waveforms with different pulse repetition frequencies (PRF) are bundled and transmitted as a single hybrid radar waveform for target measurement. At the receiver, two orthogonal signal processing channels consisting of a low PRF (LPRF) channel and a high PRF (HPRF) one, perform the extraction of target range and Doppler information, respectively. The CLEAN algorithm is innovatively used to suppress the interference from the cross-correlation residues and the autocorrelation sidelobe in the LPRF channel. The processing results, based on the proposed signal processing approach, demonstrate the technical feasibility of implementing such a signal processing scheme in radar systems. © 2007 IEEE.
