摘要
从强探测、高分辨、低截获和抗干扰角度出发,探索了一种相移键控(PSK)信号和脉冲位置调制(PPM)信号组合而成一种新的雷达信号PSK/PPM,给出了波形构造,推导了它的模糊函数。理论分析和大量的计算模拟表明组合信号具有大时宽带宽积(BT),BT相对于单一单制信号PPM提高Q倍,相对于PSK提高M倍,信号更具复杂性,且易于产生。
From the point view of strong detection, high resolution, low probability of intercept(LPI) and anti-jamming, searched a new type of radar signal PSK/PPM which composed of Phase Shift Keying(PSK) and Pulse Position Modulation(PPM), presented the waveform construction and deduced its Ambiguity Function(AF). Theory analysis and great amount of computer simulation indicate that this composed signal has high BT value. To single modulated signal PPM, hybrid signal PSK/PPMs BT value is enhanced Q times; to PSK signal, its increased M times. At the same time it is easy to generate this kind of signal with even more complexity.
