Xuegang Wang · Acta Aeronautica Et Astronautica Sinica · 2006
Wideband signals are widely used in radar,navigation,satellite communications and so on.The matched filtering or multi-subband method is generally adopted in the processing wideband signals.In this paper dechirp pulse compression processing technique is presented.Realization structure and improved measures are developed.How to select the sampling frequency is analyzed.At the same time the simulation results and performance analysis of pulse compression waveform are given.The simulation results show that the wideband linear frequency modulated(LFM) signal with 9.5 GHz center frequency,1.3 GHz bandwidth and 30μs pulse width can be processed under 90 MHz sampling frequency by means of the method.The method decreases the difficulty with the data collection in the system.
