Study on digital IQ processing method of linear frequency modulation wideband PD radar
建立了宽带PD雷达信号处理过程的数学模型,提出了高重频宽带线性调频脉冲多卜勒雷达信号的波形设计要求,以及一种单通道低采样率数字IQ处理方法.理论分析与仿真结果表明,该方法相对于传统脉冲多卜勒雷达所采用的高采样率单通道直接中频采样IQ处理方法具有更好的信号能量积累性能.
Mathematic model of signal processing is established for wideband PD radar. The special requirements for waveform-design of HPRF wideband linear-frequency-modulated pulse Doppler signal are presented. The digital IQ processing method is presented for mono-channel dada with low sampling frequency. Theoretical analysis and simulation result show that the method is superior to the method of mono-channel high-sampling-frequency direct IF sampling used in traditi…查看全部>>
