Moreover , the drivers of ccd with remote control , and the programs of interface , data acquisition , data processing and controlling , high speed laser scan system , signal receiving antenna are designed , which are debugged in the experiments . the test results of indoor experiment of the system are given 研究了ccd的弱信号检测和空间目标的定位方法，研制了远程ccd同步驱动和高速数据采集的模块化系统，设计了高速光幕扫描系统、目标光斑信号广角接收系统、 ccd驱动及远程同步、高速信号及数据处理系统，并给出了系统的性能测试结果和对目标的室内高速模拟实验结果。
Stochastic resonance ( sr ) is different from traditional methods ( such as correlation , equality superposition , filter etc ) in faint signal detection . sr can turn parts of noise energy into signal energy and enhance signal while wiping off noise , so that increasing the signal - to - noise rate ( snr ) 随机共振检测技术与传统的弱信号检测方法(如相关、平均叠加或滤波等)不同，它可以把部分噪声能量转换成信号能量，实现增强信号能量的同时去除噪声，从而提高了信噪比。
