全随机跳频脉冲信号设计与处理

对于高频雷达系统，通常很难找到一段连续可用的“寂静”频带，为了获得大的距离分辨带宽，可以离散地利用多段可用频带。然而，信号频谱的离散性会造成较高的距离旁瓣。所研究的全随机跳频脉冲信号，通过控制不同频率脉冲出现的概率可以获得较低的距离旁瓣。研究了全随机跳频脉冲信号自相关函数的统计特性，并给出了可用频带连续及非连续两种情况下的信号设计方法。

Full-random hopped-frequency waveform design and processing

For the high frequency radar system, it is difficult to find a clear wideband for operation. In order to obtain a high range resolution, transmitting/receiving waveform with discontinuous frequency bands is proposed. However, spectrum discontinuity of waveform will result in high range sidelobes. The full-random hopped frequency waveform for sidelobe suppression is investigated. By controlling the occurrence probability of different frequencies, full-random hopped-frequency waveform can achieve a low sidelobe. Statistical characteristics of the autocorrelation function are analyzed, and the waveform design methods on both continuous and discontinuous band are also given.
