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。
The traditional ground sensor system can detect a certain range of ground moving targets. Working mode is the collected signal sent back to the receiving station and then processed. This method can not be processed in real time and the reaction time is longer. This design ground sensor system consists of DSP small system, sensor conditioning and amplification circuit, asynchronous serial communication circuit, wireless transceiver module composed of four parts. The use of TMS320VC5509A as a processing chip, the use of CCS software C language program, the acquisition of the target signal through the sensor, the signal using two OPA4336 amplification, and then into the 5509A AD conversion module to the signal after the analog-to-digital conversion, running FLASH target recognition program The signal classification, and finally through the wireless transceiver module to identify the results sent to the decision-makers.
