Conducted emission and sensitivity test platform for radar emission antenna and test method of conducted emission and sensitivity test platform

Abstract

The invention discloses a conducted emission and sensitivity test platform for a radar emission antenna and a test method of the conducted emission and sensitivity test platform. The test platform comprises a test arrangement region and an equipment-under-test region, wherein the test arrangement region is a shielding chamber, in which a test instrument or test accompanying equipment is arranged;the test instrument or the test accompanying equipment is connected with equipment under test in the equipment-under-test region through a cable; the equipment-under-test region is a shielding chamber, in which the equipment under test is placed; the equipment under test is connected to the test instrument or the test accompanying equipment through a cable penetrating through a guide hole in a wall body of the shielding chamber. According to the conducted emission and sensitivity test platform for the radar emission antenna, a radar can work in a full power emission state or an approximately full power emission state, and cannot affect a human body and the equipment, so that the intactness and the accuracy of a test are improved.

Description

technical field [0001] The invention relates to the field of radar antenna testing, in particular to a radar transmitting antenna conducting emission and sensitivity testing platform and a testing method thereof. Background technique [0002] At present, with the improvement of the intelligence degree of electronic equipment, people's use of electronic equipment is getting higher and higher. The operation of a large number of electronic devices has made the electromagnetic environment in our life more complex, such as figure 1 As shown, external interference such as pulse noise, electromagnetic field emission, static electricity, lightning strikes, voltage changes, etc. will cause electronic equipment to malfunction or even be damaged, especially the interference of radio communication, radar, etc. on TV and medical equipment is more obvious. There are also potential threats to aircraft navigation. Specifically, while radar detects by emitting radar waves, it also emits el...

AI Technical Summary

Problems solved by technology

[0004] When the radar transmitting antenna is in the normal working mode, it will emit high-intensity electromagnetic waves to the outside, which will cause damage to the human body and equipment, and when the radar is transmitting at full power or close to full power, it will generate large energy and high temperature. The laboratory environment generally cannot meet the continuous high temperature test, so it can only be tested at a small power, but the test in this way cannot reflect the integrity of the test

[0005] On the other hand, if the radar is working at full power or close to the full power transmission state, the test site is usually outdoors, which is greatly affected by weather or surrounding environmental factors, and the quality of the power supply provided is poor. When the device under test is prone to sensitive phenomena
