一种舰船尾流探测系统设计

Design of Detecting System for Ship Wake

探测舰船尾流是间接探测舰船及水下航行器的一种新方法,有着广阔的应用前景。设计实现一种利用激光照射尾流气泡,通过测量气泡后向散射光空间频谱强度来探测尾流气泡的舰船尾流实时探测系统。系统设计方案采用线阵CCD光信号采集,A/D模数转换,DSP数据处理,USB接口输出四级流水线方式工作。该探测系统稳定性好,探测精度高,结果准确,有一定的先进性。

Detecting ship wake is a new method of indirect detect ship and submarine, which has broad application prospects. Design and implementation of detecting system for ship wake, which based on the laser illuminate the air bubbles in the ship wake and measure the scattered light＇s spatial spectrum intensity distribution. The system adopts the four - level pipeline structure, which consists of CCD optical signal acquisition,analog to digital converter （A/D） data acquisition, DSP processing and USB output data. The system has some advanced nature by good stability,high accuracy and good accurate.
