摘　　要：针对战斗部动爆破片数量多、速度变化范围大、破片分布范围广、测量分辨难度高的问题,该文设计了一种新型的伪码族复合连续波信号。该信号在具有图钉型的模糊函数的基础上,具有多分辨率的特性,能很好地满足测量需求。文中详细分析了这种信号的相关特性、模糊函数特性,并指出了信号存在的问题,对信号选型、数量选择和使用情况给出了建议。分析结果表明,该信号能够有效地用于战斗部动爆破片测量,对复杂波形设计和提高雷达性能具有重要意义。In this study, a new type of Continuous Wave （CW） signal modulated by pseudocode family is designed, solving the problem of more quantity of warhead dynamic fragments, larger speed variation, larger distribution and more difficult resolution during the measurement of warhead dynamic fragments. This signal has thumbtack ambiguity function and multiresolution characteristics. It can meet the measurement needs very well. Herein, correlation properties and ambiguity function characteristics of this signal are analyzed. Moreover, the signal’s limitations are reported. Recommendations pertaining to signal selection, number option, and usage are presented. The analysis results show that this signal can be used for dynamic fragments measurement of warhead. This signal is also of great importance to improve complex waveform design and radar performance.
