Abstract

The invention discloses a microwave measurement and communication system for rendezvous and docking. The system comprises a main unit and an auxiliary unit, wherein the main unit is arranged on a tracking aircraft; the auxiliary unit is arranged on a target aircraft; the main unit comprises a main unit frequency source, a main unit signal processor, a main unit modulation transmitting channel, a main unit receiving channel, an angle measurement receiving channel, a main unit duplex coupler and a main unit antenna array; and the auxiliary unit comprises an auxiliary unit frequency source, an auxiliary unit signal processor, an auxiliary unit modulation transmitting channel, an auxiliary unit receiving channel, an auxiliary unit duplex coupler and an auxiliary unit antenna. Meanwhile, the invention also provides a microwave measurement and communication method for the rendezvous and docking employing the device. By the invention, under the conditions of large dynamic distance range and wide viewing angle between the tracking aircraft and the target aircraft, the distance, speed and angle of the target aircraft are measured by the tracking aircraft, and data communication between thetracking aircraft and the target aircraft is realized.

Description

technical field [0001] The invention relates to a microwave measurement and communication system and method for rendezvous and docking. Background technique [0002] At present, the microwave measurement and communication of rendezvous and docking in foreign countries adopts the traditional system of microwave radar, and some of them have communication functions through time-sharing applications. my country has also developed microwave radar in the rendezvous and docking project between the manned spacecraft and Tiangong-1, but the distance measurement and speed measurement of these devices adopt the traditional response system. The technologies used for angle measurement include amplitude ratio monopulse tracking angle measurement and interferometer angle measurement, working in L, S, X, Ku and other frequency bands. Typical and representative, for example, the space shuttle developed by Hughes Corporation of the United States is used for rendezvous, docking and communicat...

AI Technical Summary

Problems solved by technology

In lunar orbit rendezvous and docking, microwave radar is the core sensor and communication equipment for medium and long-range measurements. In lunar orbit rendezvous and docking, GPS measurement channels are no longer available, and there are few available measurement and communication channels, and there is a high demand for lightweight , the shortcomings of existing microwave measurement systems for rendezvous and docking are: the weight and power consumption are too large when integrating multiple functions using the traditional system, and the multi-functional system configuration and processing methods are difficult to solve high measurement accuracy and wide coverage , the contradiction between multifunctional integration and product lightweight, resulting in the limitations of the application of these methods
