摘要
该文提出了一种利用随机多元码脉位调制(PPM)和脉间伪随机或随机二元序列相位调制(PM)相结合的混合波形设计方法。推导并分析了这种混合波形的平均模糊函数。结果表明这种混合波形不仅具有结构简单、易于处理等特点,而且具有良好的测距和测速性能,以及良好的ECCM性能。
The design method for hybrid waveforms utilizing ran-dom poly-cell code pulse position modulation (PPM) and pulse-to-pulse binary sequences phase modulation (PM) is introduced in thispaper. Average ambiguty function of the hybrid waveforms is de-duced and analyzed. It is shown that the hybrid waveforms not onlyhave simple structure and convenient processing, but also good reso-lution of the distance and the velocity, and good charactristics of EC-CM.
