According to the power testing device based on the forward-tilting beam, the X-direction moving carrying platform, the lifting support and the triangular tilting support are adopted, the position and the forward-tilting angle [theta] of the to-be-tested antenna on the X axis and the Z axis can be accurately adjusted, accurate alignment of the forward-tilting beam of millimeter waves and the millimeter wave receiving and transmitting unit is achieved, and the power of the forward-tilting beam ofthe millimeter waves can be tested.

Description

technical field [0001] The invention belongs to the field of electronic technology, and in particular relates to a power testing device and a testing method based on a forward-tilted beam. Background technique [0002] Due to its strong ability to resist rain and fog interference, the millimeter wave detector has become one of the main technical means for modern air target detection and obstacle avoidance. Due to the short rendezvous time between the aircraft and the target during flight, the beam of the millimeter-wave detector is designed with a forward tilt, which can increase the rendezvous time and obtain a better recognition rate, which has attracted attention in modern air target detection applications. [0003] Accurate power testing technology for millimeter-wave detectors has always been a difficult problem in the development of millimeter-wave technology. Existing researches mainly focus on the test research of intelligent transportation radar. Due to the large t...

AI Technical Summary

Problems solved by technology

[0005] 1) Without a three-dimensional calibration system, conventional test equipment, without a three-dimensional calibration device, the accurate direction of the main beam cannot be obtained, which will cause the deviation of the test direction, and the data obtained by the test cannot reflect the actual power of the main beam, resulting in errors

[0006] 2) The uncertainty of testing for small targets is high

It is mainly aimed at the detection of high-power radar signals. For the detectors of weak signal detection, the transmission power is small, and this test method cannot be accurately detected, and the uncertainty is generally greater than 20%.

[0007] 3) Conventional testing devices use manual testing, which has low testing efficiency and is not suitable for batch testing
