| 摘 要： | 从高分辨、抗干扰、低截获角度出发，提出一种新的扩频信号。这种信号是线性调频与非周期伪随机编码信号及线性调频连续波与周期伪随机编码信号组成的一种新型信号。理论分析和大量的计算机模拟结果证明了这种新型扩频信号的有效性。另外，用数字方法实现了这种波形的宽带波形产生器。这种产生器可以产生任意幅度和相位调制的信号。同时给出这种宽带信号用声表面波技术处理的方法。

| Abstract: | This paper purposes o intreduce a new spread spotrum sigrial with high resolution lowprobability of intereept and higti porformance of ECM. One kind of new signal is obtained by comdining theLFM with the non-poriodic poudo-random apuences. Another kind of signal is obtained by combining theLFM with the poriodic poudo-random sequences. Theoretital analysis and computer simulation results aregiven to show the effectivenase of the new signal. In addition ,a widebend waveform generator is realized,using digital techniques. The niethod of this sigrial prnsing is given by SAW. Digital techniques can easilygenerate wave formis with artritrary amplitude and phase niodulation. |
