    • A radar test system for testing a collision avoidance radar system. The radar test system includes circuitry to downconvert a signal from the collision avoidance radar to an intermediate frequency signal, to delay the intermediate frequency signal to simulate the delay of a return signal from an object located a particular distance from the collision avoidance radar system, and to upconvert and transmit the intermediate frequency signal back to the collision avoidance radar system to determine if the collision avoidance radar system provides accurate distance readings. The radar test system further couples the intermediate frequency signal to a spectrum analyzer. The spectrum analyzer can be used to determine if the collision avoidance radar system is operating within the 76-77 GHz frequency band allocated by the Federal Communications Commission (FCC). The radar test system further couples the intermediate frequency signal to a power meter. The power meter can be utilized to determine the power of the signal transmitted from the collision avoidance radar system.
    • 一种用于测试避碰雷达系统的雷达测试系统。 雷达测试系统包括将来自防撞雷达的信号下变频到中频信号的电路,以延迟中频信号以模拟来自位于与碰撞避免雷达系统特定距离的物体的返回信号的延迟;以及 将中频信号上变频并发送回避雷系统,以确定避碰雷达系统是否提供准确的距离读数。 雷达测试系统还将中频信号耦合到频谱分析仪。 频谱分析仪可用于确定碰撞避免雷达系统是否在由联邦通信委员会(FCC)分配的76-77 GHz频段内运行。 雷达测试系统还将中频信号耦合到功率计。 功率计可用于确定从避碰雷达系统传输的信号的功率。
