摘　　要：声光信号处理技术具有大瞬时带宽、大动态范围和高速并行处理能力,而频谱分析技术是其重要的研究分支。首先介绍了声光信号处理在电子侦察频谱分析中的原理,然后分别针对功率型和外差型两种频谱分析实现方式进行了探讨,给出了声光侦察接收系统与其它传统电子侦察系统的性能对比,最后对其应用前景进行了展望。Acousto-optic signal processing has the abilities of wide instantaneous bandwidth, high dynamic range and high-speed parallel process, and spectrum analysis is one of important research fields. The basic principles of acousto-optic signal processing in electronic reconnaissance and spectrum analysis are introduced firstly, and then the two implementations such as power spectrum analyzer and heterodyne spectrum analyzer are discussed. The performance of traditional electronic reconnaissance system is compared with acousto - optic reconnaissance system, and finally it is indicated that this system has wide application prospects in future.
