Multi-station radar positioning system

Abstract

The invention discloses a multi-station radar positioning system which comprises a plurality of movable radar single stations and a processing center communicated with the plurality of movable radar single stations respectively. The movable radar single station comprises a movable platform, a radar detection unit carried on the movable platform, a satellite positioning time service unit and a wireless communication unit, the processing center comprises a parameter setting unit and a calculation unit, the parameter setting unit is used for setting the number, position coordinates and detectiondirections of the radar single stations, and the calculation unit collects the target information returned by the radar single stations and calculates the coordinates of a target through a positioningalgorithm so as to position the target. Compared with a single-station radar, the target information can be detected at multiple angles, and the positioning precision is high; compared with a traditional multi-station radar, the configuration is more flexible, and all radar single stations are erected on the movable platform. The system can be constructed and debugged within several hours to several days, so that the multi-station radar construction and debugging time is greatly shortened, and the system is more suitable for being applied to the complex and changeable battlefield detection environments.

Description

technical field [0001] The invention relates to the field of radar positioning, in particular to a multi-station radar positioning system. Background technique [0002] Radar plays a pivotal role in the military field. It is called the commander's eyes and can detect, locate and track potential threats such as aircraft, ships and armed vehicles at a long distance. With the development of stealth technology, the reflection cross-sectional area of ​​the target in a certain detection direction can be made very small, making it difficult for single-station radar to detect the target outside the security warning range. Multi-station radar can detect targets from multiple angles and enhance the detection performance of radar system targets. It is a kind of detection equipment with great potential. [0003] In the current multi-station radar system, the location of each station is fixed, and each radar station and the information processing center are transmitted through a wired m...
