Problems solved by technology
[0004] At present, in the testability design of the main control software of the radar system, we are faced with a problem that is difficult to solve, that is, when the main control software of the radar system generally only considers the failure of other parts of the radar, it summarizes the reported fault information and reports the fault code. The failure of the radar frame signal and the signal related to the radar frame that the radar operation depends on is not considered, resulting in the entire radar not working normally, the radar picture is unstable, and the fault information cannot be reported. Only manual judgment can be made, which greatly reduces the BIT of the radar. Test your ability

The present invention relates to the technical field of radar testing, and specifically provides a radar frame fault detection method. First, the radar frame signal is obtained within the first set time, and it is judged whether the acquired radar frame signal is greater than or equal to the first set number, and if so, then Send the radar state data packet to the radar frame fault detection device, otherwise do not send the radar state data packet to the radar frame fault detection device, then judge whether the number of the radar state data packets obtained by the radar frame fault detection device in the second set time If it is greater than or equal to the second set number, if it is, the radar frame signal is considered correct, otherwise it is considered that the radar frame signal is faulty; this method can complete the detection of radar frame signal faults only by modifying the main control software of the radar system, and does not need manual long-term Time judgment, and adopts two-level judgment method to prevent the occurrence of false alarms, and has strong stability.
Description
technical field [0001] The invention relates to the technical field of radar testing, in particular to a radar frame fault detection method. Background technique [0002] Testability is a design characteristic of a product (system, subsystem, device, or component) that can promptly and accurately determine its state (workable, non-workable, or degraded) and isolate its internal faults. [0003] Built-in testing (BIT) is defined as the automated testing capability provided within a system or device to detect and isolate faults. BIT is an important technology to improve the testability of a system or equipment. It is used to periodically or continuously monitor the operating status of the system, and to observe or diagnose before maintenance. [0004] At present, in the testability design of the main control software of the radar system, we are faced with a problem that is difficult to solve, that is, when the main control software of the radar system generally only considers...
