Abstract

The invention relates to a high-accuracy pulse power detection module which comprises a radio-frequency circuit for receiving a radio-frequency input sampling signal and a radio-frequency output sampling signal. An output end of the radio-frequency circuit is connected with an input end of a detection circuit for receiving sampling voltage V1 and sampling voltage V2, and an output end of the detection circuit is connected with a fault indication circuit. The high-accuracy pulse power detection module can simultaneously detect an over-temperature connecting point, voltage V1 sampling, voltage V2 sampling, radio-frequency input sampling and radio-frequency output sampling, can monitor input and output power variation of a forestage component in real time to accurately judge whether input power and output power are faulted or not, voltage stability can be monitored in rear time to accurately judge whether an under-voltage condition exists as voltage reduces or not, no power output is caused, fault reasons can be effectively and rapidly found, and the component is conveniently maintained.

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...
