Abstract

The invention provides an isolator reverse power tolerance test system and method. The method includes steps: an original single-carrier signal emitted by a signal source is amplified through a microwave power amplifier and provided to a first power meter and a vacuum tank through a first dual directional coupler; the first power meter measures a power value of the original single-carrier signal and forms a first power value; an isolator is arranged in the vacuum tank; the original single-carrier signal is provided to a second forward coupler through the isolator and provided to a short circuit block through the second forward coupler; the original single-carrier signal enters the short circuit block for reverse transmission after delay, a reverse carrier signal is formed, and the reversecarrier signal passes through the second forward coupler and the isolator and is provided to the first dual directional coupler and a third power meter; the third power meter measures a power value ofthe reverse carrier signal and forms a third power value; a synthesis signal power value is obtained through calculation according to the first power value; and a reverse isolation degree is obtainedaccording to the synthesis signal power value and the third power value.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to an isolator reverse power withstand test system and method. Background technique [0002] At present, with the improvement of remote sensing observation capabilities, remote sensing satellites are showing a rapid development momentum. The payloads carried by remote sensing satellites are gradually developing into multiple methods and diversification. Hyperspectral and multispectral payloads bring higher-precision and higher-resolution image effects, and at the same time generate more and more payload data. In order to meet the high-speed downlink requirements of massive data from low-orbit remote sensing satellites, it is necessary to increase the satellite-to-ground data transmission rate. [0003] In a certain satellite model, calculating the effective data and transit time generated by an optical payload every day, it can be concluded that the satellite-ground data rate is...
