摘　　要：本文选取了两条不同的单道地震接收电缆（AAE接收电缆、GEO接收电缆）在野外采集到的原始数据，并利用快速傅立叶变换（FFT）以及S变换等方法，从数据本身、频率域、时频域方面进行了对比分析。结果表明接收段较短、且内部检波器组合更紧致的AAE电缆具有较高的浅层分辨率，更适合于浅水作业，而接收段较长，检波器较多，检波器间距稍大的GEO电缆可以采集到高信噪比的资料，更适合于深水作业。In this paper we collect the raw data from two different single-channel reflection seismic streamers （AAE streamers and GEO streamers） and analyze those data comparatively from frequency domain and time -frequency domain by using fast Fourier transform （FFT） and S - transform. The result shows that AAE streamers which have shorter receiving section and compact geophones can get higher shallow resolution and therefore are more suitable for shallow water. While GEO streamers are more suitable for deep water because of its longer receiving section , more geophones , and the ability to acquire high signal-to-noise ratio data with longer span between geophones.
