The Research On The Method Of Laser Warning Signal Reception And Processing

This article has researched the method of laser alarm signal receive and the processing, and has discussed the software and hardware design and the principle of work of laser pre warning system in detail.The thesis has mainly done several aspect design research as follows:1. According the principle of laser detection, it proposed overall design project of system.It mainly composed of four parts: The electro-optical signal survey part, the weak signal enlargement part, the signal peak value maintains the part, DSP signal gathering and the transmission part.2. It has designed hardware circuit of system, which included the signal receive, the enlargement, the peak value maintain, DSP signal gathering.3. It has designed the intelligence transmission module, which carries on the data transmission using DSP internal serial communication module (SCI).4. It has designed the data processing and the contact surface display module, which carries on processing to the data to demonstrate use visualization procedure Visual Basic, and can analysis laser signal intensity and position direct-viewing.Through the above several parts of designs, it has completed this article research content, and has built the foundation for further research of the laser warning system.
