Problems solved by technology

The communication extension connected to the radar system adopts advanced digital communication technology. Except for high-frequency analog circuits, most of them are digital circuits. Although they have certain self-inspection functions, they are like computer motherboards. Accurate judgment and maintenance of faults
[0004] The traditional fault analysis and troubleshooting method mainly uses fault diagnosis equipment to obtain the signal information of the plug-in, and then uses experienced technicians to analyze and judge the signal, and finally obtains the fault status of the system plug-in. This fault analysis and troubleshooting method is a It is time-consuming and laborious for technicians, and the fault judgment of plug-ins depends on the experience of technicians

Description

technical field [0001] The invention belongs to the field of radar communication detection and relates to a detection method based on a radar system communication extension detection device. Background technique [0002] All extensions of the high-mobility vehicle-mounted three-dimensional solid-state radar are installed on two trucks (antenna truck and terminal truck), and a complete radar system is connected by the communication extension. There is a radar system communication extension on the terminal car and the antenna car respectively, and the two extensions are connected through a communication medium (ie, a communication cable). The communication extension mainly includes the communication medium (the communication cable connecting the antenna car and the terminal car), the transceiver module (mainly including the radio frequency module) and the communication plug-in; when two vehicles communicate, the communication plug-in generates communication information, and th...
