Description

technical field [0001] The invention relates to the technical field of microwave imaging, in particular to a synthetic aperture radar antenna stabilization platform comprehensive test system. Background technique [0002] Synthetic Aperture Radar (SAR) is a high-resolution microwave imaging radar, which has the advantages of all-day, all-weather, and resolution not affected by the height of the carrier platform. SAR plays a very important role in land survey, environment and disaster monitoring, ocean observation, sea surface pollutant monitoring, topographic surveying and mapping, resource exploration, interstellar surveying, etc. in the civilian field. [0003] Antenna stabilization platform is an important part of airborne synthetic aperture radar, which is generally composed of motor, motor drive, gyroscope, mechanical platform and control circuit. Its main function is to follow the inertial navigation parameters while isolating the carrier aircraft and atmospheric dist...

AI Technical Summary

Problems solved by technology

[0005] In the development and production process of the Synthetic Aperture Radar Antenna Platform (SARAP), the traditional testing and calibration methods (that is, the testing and calibration methods based on non-specialized methods) are relatively cumbersome: that is, the functions of the SARAP Modules (PWM control module, power amplifier module, drive motor, gyroscope module, acquisition module, etc.) are calibrated, and the performance of the SARAP machine is also tested and calibrated

The test equipment and cable connection methods required for the calibration of each functional module and the whole machine are different, and the control software used is also different, which brings a complicated workload to the test personnel.

At the same time, since the antenna stabilization platform has a weak current (measurement and control circuit) part and a strong current (motor drive circuit) part, the requirements for cable shielding characteristics and anti-interference characteristics are relatively high during calibration. These factors also increase the test and calibration. difficulty
