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.
本文研究了随机脉冲位置调制与脉冲之间随机相位调制相结合的脉冲多卜勒雷达信号。

The transmitted signals which were modulated is a group of orthogonal sine signals as subcarrier and non-regular zero square waves that the code elements period is t as baseband coded formats.
