【摘要】 毫米波雷达硬件体积小、探测精度高和全天候工作等特点,不仅具有很高的隐蔽性和很好的抗干扰性能,同时兼有微波和红外探测的优点,近年来受到了广泛重视。文中提出一种基于线性频率调制连续波雷达的汽车防碰预警系统,给出了系统的基本结构,并对前端数据采集、数据缓存和PC104数据引入3部分进行分析设计,最后通过系统联调实现了汽车防碰预警等功能。更多还原

【Abstract】 The millimeter-wave radar has been paid wide attention to in recent years due to its working methods of active target detection and capability of working at all time,small volume,high covertness and good anti-jamming performance.At the same time it has the advantage of microwave and infrared detection.In this paper,a millimeter-wave radar which is based on automobile collision preventing system is proposed,and the basic configuration of the system is composed of front-end data collection,data caching and data input to PC104.Finally we implemented function of preventing from and alarming of the automobile collision accident by system joint adjustment.更多还原
