Wide-Band High Resolution Homing Sonar Echo Detect Based On Spread Spectrum Technology

摘要：

This paper propose and analyze high resolution auto-navigation sonar system based on DS/SS technology. Compare to traditional auto-navigation sonar system, the system have big time and frequency range, can provide high distance and speed resolution and good anti-interference capability. Paper discuss the principle of waveform design and enduce ambiguity function of DS/SS modulation signals. In the case of high-speed target, paper provided and proved a algorithm using CZT which can estimate Doppler frequency offset and target speed in very low SNR condition.
