摘要: 本文研究了隨機脈沖位置調(diào)制與脈沖之間隨機相位調(diào)制相結(jié)合的脈沖多普勒雷達信號。首次給出了該隨機序列的模糊函數(shù)數(shù)學表達式,對其推導所采用的主要方法作了敘述,研究了該序列的產(chǎn)生方案,最后對結(jié)果進行了分析。

Abstract: In this paper, a PD radar signal is researched, which is modulated by randomly staggered pulse sequence whose phase is also modulated by random binary-phase code. The expression of its ambiguity function is firstly presented, the main derived method is also given, and how to generate this pulse sequence is discussed. Finally simulation results are analyzed. -
