Orthogonal Two-Channel Processing Of Hybrid Coding Waveform
A novel waveform which consists of a pair of orthogonal coding waveforms transmitted in High pulse repetition frequencies (PRF) and Low pulse repetition frequencies (LPRF) has been proposed At the receiver,two signal processing channels perform the extraction of target range and Doppler information Although two processing channels matches coding waveform,there still exists interference of the cross-correlation residues and auto-correlation sidelobes which effects the performance of the whole radar. Traditional method such as Matched filter and CLEAN algorithm cannot remove the interference inan optimal way.In This paper,Orthogonal two-channel processing method is proposed to adaptively suppress the interferenceInthe Mean Square Error (MSE) sense and so the two signal processing channel can be thought to be completely orthogonal at every delay time. The signal processing scheme based on it is developed Target range and Doppler information of high resolution can be extracted simultaneously.
