The invention discloses a deep-buried equivalent communication test system after impact of a deep-space impactor. The test system is composed of a deep-space environment simulation cabin, a microwave anechoic chamber, an impactor, a target, and signal receiving and testing equipment. The microwave anechoic chamber is set in the deep space environment simulation cabin, the target is built in the microwave anechoic chamber, the impactor is buried in the target, and the signal received by the signal receiving test equipment from the communication module in the impactor through the signal transmitting antenna simulates the deep space impactor Post-collision deep-buried equivalent communication test, to test the communication performance of the deep space impactor after collision. By setting targets of different materials in the microwave anechoic chamber, considering different conditions such as the depth and shape of the crater, the signal quality of the communication module in the impactor under different working conditions is simulated and tested. The post-collision deep burial equivalent communication test method of the deep space impactor is simple, reliable, and easy to implement, which can meet the requirements of the deep space impactor post-collision deep burial equivalent communication test and lay the foundation for the development of deep space post-collision deep burial communication technology in the future .
Description
technical field [0001] The invention belongs to the technical field of earth satellites or other deep-space exploration aircraft, and in particular relates to a deep-buried equivalent communication test system after impact of a deep-space impactor. Background technique [0002] The deep space exploration mission is a complex systematic project. Impact penetration detection is one of the efficient means to realize the internal detection of extraterrestrial objects in deep space. It has the characteristics of simple structure, high integration, flexible configuration, etc., and consumes less resources. It can penetrate into the interior of celestial bodies and carry out various forms of scientific tasks such as in-situ detection and sampling return. It has broad application prospects in deep space exploration and other fields. [0003] After the deep space impactor crashes into the target celestial body, it can continue to carry out scientific experiments inside and send the t...
