整个系统包括多屏图象、语音引导、多工位多通道信号采集和处理、车辆识别和跟踪等。
It includes multiscreen image and phoneme guiding, multi-working sites and multi-channel signal gathering and processing, identifying and tracing of vehicles, etc.
通过对信号进行基于瞬时自相关的瞬时频率提取的方法对中频信号进行分析、识别，然后可以在FP - GA内部构造一个多通道匹配滤波器对信号进行匹配。
The article analyses the signal through the method of gaining instant frequency on the base of instant correlation, then we can make up a multicenter matching filter in the FPGA.
