Contour modulation is a technique in which a phase-modulatedsignal waveform and amplifier output impedance work together to maintain higher efficiency over a sizable output power back-off.
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 sound signal is Doppler FM modulated based on the analysis of the moving track of the original source, and then phase modulated according to the interaural time difference.
