摘　　要：本文是对非连续谱雷达信号体制的研究,结合了相位编码信号和跳频信号提出一种脉内调相脉间跳频信号。研究了该信号提取信息的处理方法,根据其信号形式,对相同载频频率的不同脉冲,实现脉间多普勒处理,通过对回波信号的频谱变换获得目标的速度信息。根据信号的编码特性应用采样相关进行距离处理。仿真结果表明该方法可获得比较理想的速度、距离信息。This paper analyzes discontinuous spectra radar signal system, proposing a intra-pulse phase modulation and inter-pulses frequency hopping signal which combines phase-coded signals and frequency-hopping signals. It studies the signal to withdraw treatment of information, according to its signal form, to the different pulse which same signal carrier frequency, it carry out Doppler processing pulse to pulse. And it can acquire the speed information of target through returning a echo signal from spectrum transform. According to encoding characteristic of signal, correlation sampling is used to spacing treatment. Simulation result shows that the method can gain more ideal speed and distance information.
