Detection And Recognition Technology Of Entity Target Which In Somke By Linear Array Sensor

Laser has been already widely used in various types of weapons and equipments as a good direction, high precision, strong electromagnetic interference resistance and other advantages. But, laser fuze is easily affected by natural environment, cloud, mist, rain and snow and battlefield dust will transfer to the laser caused by decay, but also this dust will produce after the formation of laser scattering echo interference, Cloud (dust) echo interference generated may cause the fuze warhead false alarm, the early explosion or fire, and smoke interference can not be ignored. At present, a lot of laser detection system in anti smoke interference has done in-depth research in the field of computer software, using more theoretical research on laser simulation after scattering.In the actual test, as the uncertainties of smoke itself is great, extracting entity from the smoke has certain difficulty。As this article, it using linear array sensor receives the echo which emit from the puls laser, using triangulation, to extract the target signals from the smoke in battlefield. Through the experiment, combining method of data analysis and signal processing to improve laser detection and recognition ability of proximity weapons on targets. To eliminate the interference of battlefield smoke from a certain extent, improve the efficiency of fuze-warhead coordination, so that the laser proximity fuze technology get further development...
