Abstract

The invention relates to a high-precision pulse power detection module, which includes a radio frequency circuit for receiving radio frequency input sampling signals and radio frequency output sampling signals, the output end of the radio frequency circuit and the input of the detection circuit for receiving sampling voltage V1 and sampling voltage V2 The output terminal of the detection circuit is connected with the fault indication circuit. The present invention can simultaneously detect the over-temperature contact, voltage V1 sampling, voltage V2 sampling, radio frequency input sampling, and radio frequency output sampling, and can monitor the input and output power changes of the front-stage components in real time, and then accurately judge whether the input power and output power are faulty, It can monitor the stability of the voltage in real time, and then accurately judge whether it is an undervoltage state caused by a voltage drop, resulting in no power output, which can effectively and quickly find the cause of the fault and facilitate maintenance.

Description

technical field [0001] The invention relates to the technical field of radar detection, in particular to a high-precision pulse power detection module. Background technique [0002] With the rapid development of electronic technology, while the radar function is perfect, it also increases the complexity of radar technology, making it more dependent on the internal inspection equipment (BITE) in maintenance. With the development of the detection module, the fault location time, which accounts for the main share of the maintenance time, is greatly shortened. Fault detection technology is mainly to study how to find the fault location early and quickly eliminate the fault. It has an online detection function and can quickly and accurately locate the fault. Existing detection modules are too large in size and heavy in weight, which cannot effectively resist the interference of external power supply voltage fluctuations, and easily cause high false alarm rates. With the complex...
