程序
说明: 当今世界电子对抗日益激烈,对于雷达低截获和抗干扰能力的研究越来越受到关注。OFDM (Orthorgonal Frequency Division Multiplexing,正交频分复用)雷达具有大时宽带宽积、波形设计方法灵活、频谱利用率较高以及低截获性能好的特性,因此逐渐成为雷达领域的重点研究方向。除此之外,OFDM信号时域和频域波形都比较复杂,当雷达信号采用OFDM技术时,敌方很难精确估计发射信号波形和瞬时频率,使得截获机不容易分析出检测到的雷达信号。当面对敌方的欺骗式干扰时,对于同样具有大时宽带宽积的线性调频信号,OFDM信号具有更好的抗欺骗式干扰的性能,因此OFDM技术在雷达上的运用愈来愈得到关注。(As electronic warfare becomes increasingly fierce, low intercept probability radar has become an important research filed in electronic countermeasures. OFDM (Orthorgonal Frequency Division Multiplexing) radars have gradually emerged due to their high spectrum efficiency, large time-bandwidth product, flexible waveform design methods, and low intercept probability.In addition, because of the complex time-frequency characteristics of the transmitted signal in OFDM radar, the enemy is difficult to estimate the transmitted signal waveform and instantaneous frequency.When faced with enemy deception interference, OFDM signals have better anti-spoofing performance for LFM signals that also have a large time-bandwidth bandwidth product. Therefore, the use of OFDM technology in radar is attracting more and more attention. .)
