System for high-precision correction of monitoring radar measurement error and correction method

Abstract

The invention relates to the field of a radar measurement error modification technology, more particularly to a system for high-precision correction of a monitoring radar measurement error and a correction method. The system is composed of a server, a radar, a monitoring operation terminal, and an intelligent terminal. The server is based on the Internet and is provided with a public coordinate forwarding module. The monitoring operation terminal and a radar carry out information exchange and is superposed with a digital map. The intelligent terminal including a coordinate obtaining and reporting module reports coordinate information of the location point of the intelligent terminal to the server by a mobile base station; and the server forwards the received location point coordinate information to the monitoring operation terminal by the internet. With cooperation with a target, pure radial movement and pure tangential movement are made to correct an angle and a distance error. The system has the following advantages: when a mobile carrier carries the intelligent terminal, a geodetic coordinate system and radar coordinate system are normalized to realize high-precision positioning displaying of a target trace point in a practical map, so that monitoring information outputted by a radar terminal becomes precise.

Description

technical field [0001] The invention relates to the technical field of methods for correcting radar measurement errors, in particular to a high-precision system and correction method for correcting surveillance radar measurement errors. Background technique [0002] The result information of radar detection includes distance, angle, speed, etc. Generally, the focus is on the distance and azimuth of the target, that is, accurate positioning. Therefore, the acquisition of azimuth and distance information is the main function of surveillance radar. [0003] Based on the principle of radar, there are certain systematic errors in the distance and angle information of the detected points; in addition, the installation error formed by the deviation angle between the mechanical zero position and the true north when the radar station is deployed will have a relatively large impact on the radar measurement accuracy. big impact. In particular, after the radar terminal superimposes th...

[0011] 2) The operation process is cumbersome

For example, in adverse weather conditions such as high cold and strong wind, the operator may not be able to achieve the purpose of accurate calibration due to his own reasons;

[0013] To sum up, this traditional method has many defects in the field of surveillance radar for rapid mobile deployment, and it is difficult to meet the needs of rapid mobile deployment.
