随机二相码PD雷达信号及其平均模糊函数

Random Binary-Phase-Code PD Radar Signal and Its Average Ambiguity Function

本文提出了用随机二元码调相和相干脉冲调幅得到随机信号雷达波形的新方法。推导出该波形的平均模糊函数。分析模糊图表明，该波形同时具有优良的无距离模糊和速度模糊的双重性能，是一种适合于取代周期性脉冲确定序列的随机信号雷达波形。

This paper proposes a new method for obtaining a random signal radar wavefonn by means of random binary code PM and coherent pulse AM.After the average ambiguity of the waveform is developed,it is shown that the waveform has good characteristics of measuring both the range and the velocity unambiguously by analyzing ambiguity surface.And the waveform is suitable to replace the periodical pulse deteiministic sequence.
