摘　　要：声光信号处理技术是以声光器件为核心的频谱分析技术和相关处理技术,具有大瞬时带宽、大动态范围、高处理增益和高速并行能力。根据非相干时间积分声光相关器原理,针对巴克码相关峰提取问题,提出了多项式拟合和小波变换两种峰值提取方法,对两种方法进行了比较,并对实验结果进行了分析。Acousto-optic signal processing is a sort of technology of spectrum analysis and correlation,taking acousto-optic device as the core,with the features of large instantaneous bandwidth,dynamic range,processing gain and high speed parallel capacity.According to the principle of incoherent time-integrating correlator,the methods of polynomial fitting and wavelet transform are used to resolve the problem of correlation peak extraction of baker code.At last,experimental results and comparison of two methods are also given.
