摘要
本文首先指出常规雷达使用的恒载频脉冲信号的局限性和可压缩大时宽带宽积信号的优越性,用模糊函数从波形和频谱分析了几种大时宽带宽积信号的主要特性。提出了这种信号在交管雷达中应用的必要性,探讨了其可行性,最后对应用的前景进行了展望。
At the beginning of the paper,the limitation of the carry-frequency-constant pulse signals used in general marine radars and the advantages ofcompressable large time-bandwidth signals are pointed out.Then the char-acteristics of the waveform and frequency spectrum of large time-bandwidthsignals are analysed with ambiguity functions.The necessity of applyingthe large time-bandwidth signals to the radars of VTS is confirmed and thefeasibility is probed into.Finally,the prospect of such application is dis-cussed.
