摘要
把一种称为特征序列的二元伪随机序列引入二相编码脉冲压缩雷达信号的设计中。为积累码组和频率分集长短码信号的优化和应用,从而提高信号主副比和改善其多普勒容限创造了条件。文中给出了信号压缩比为400时的设计实例。
One kind of biphase pseudorandom sequences, called characteristic sequences, are used in the waveform designs of biphase coded radars to optimize signals of integration code sets and frequency diversty long-short codes. This makes it possible to improve the output peak ratio of mainlobe to sidelohe (RMS) and signal Doppler tolerance. The optimization results of signals with compression ratio 400 are given.
