Maximum sidelobe suppression for quasi-random step frequency signal and its neural network implementation

  • 摘要: 高頻雷達(dá)工作在電磁環(huán)境十分惡劣的短波段,為避開干擾嚴(yán)重的頻段,采用一種準(zhǔn)隨機(jī)跳頻信號(hào)。這種信號(hào)經(jīng)匹配處理后距離旁瓣很高,嚴(yán)重影響了雷達(dá)的性能。該文詳細(xì)地分析了這種信號(hào),提出一種距離旁瓣處理技術(shù),并采用神經(jīng)網(wǎng)絡(luò)來(lái)實(shí)現(xiàn)優(yōu)化計(jì)算.仿真表明算法具有較好的數(shù)值穩(wěn)定性,能有效地抑制最大旁瓣。
    Abstract: Operating in the heavy congested SW band, HF radars use a quasi-random step frequency signal to avoid the interference bands. However, the sidelobe of this signal after matching processing is very high, thus would greatly debase the radars performance. In this paper, a range sidelobe processing technique is proposed on a basis of delicate signal analysis and a NN based algorithm is applied to realize the optimization computing. Simulation re-sults demonstrate this method could successfully suppress the maximum sidelobe with good numerical stability.
