摘要
传统的地面传感器系统可以探测一定范围内的地面运动目标。工作模式是把采集到的信号发回接收站再进行处理。这种方法不能实时处理且反应时间较长。本文设计的地面传感器系统由DSP小系统、传感器调理及放大电路、异步串口通信电路、无线收发模块四部分组成。采用TMS320VC5509A作为处理芯片,利用CCS软件编写C语言程序,通过传感器采集目标信号,运用OPA4336将信号两级放大,再送入5509A的AD转换模块将信号进行模数转换以后,运行FLASH中的目标识别程序将信号分类,最后通过无线收发模块将识别的结果发送给决策者。
Traditional unattended ground sensor system can detect the targets moving on the ground in a certain range. Its working mode is to send the acquired signal back to the receiving station, then process the signal. This method couldn＇t make real-time processing and need longer reaction time. The proposed unattended ground sensor system is composed of DSP small system, the conditioning and amplifying circuit of the sensor, asynchronous serial port circuit, and wireless transceiver module. TMS320VC5509A is used as processing chip, CCS software is used to compile C language program, the signal of the targets are acquired with sensors, and the signal is two-stage amplified using OPA4336, and then transmitted to A/D converter of 5509A.After A/D conversion, the signal is classified the signal with target identification program in FLASH, and finally sent the discriminating outcomes to the receiving station with wireless transceiver module.
