Embodiment 2

[0058] Embodiment 2: Synchronous Rotation Control Mode

[0059] In the multi-antenna cooperative control method of the present invention, the control process of the method is as follows:

[0060] Turn on the system, initialize the system, and then enter the following control process according to the control instructions:

[0061] a) First (on the host computer or the LCD screen of this control) set any radar antenna as the reference machine, and other radars are automatically defaulted as slave radars; the synchronous machine of each radar antenna sends the real-time data of the machine to the main control unit in real time. Azimuth value, the main control unit reads the azimuth value θ(t) of the reference radar and the azimuth value θn(t) of the slave radar, and calculates the azimuth difference between the slave radar and the reference radar ε(t)=θ(t) -θn(t), if ε(t)<0, then add 360° to this value, which means that it can only be chased in a unified clockwise direction;

Abstract

The invention provides a multi-radar antenna coordination control method. Multiple radars can be freely selected to work cooperatively and one radar can be controlled freely through coordination control over multiple radar antennae; through co-work of the multiple radars, working efficiency is improved, and cooperative work which can not be completed before is completed. The control method has the advantages that multi-radar antenna synchronous revolution control can be achieved, and namely multiple radars needing coordination rotate in the manner of keeping identical orientations and basically identical speeds as a standard radar all the time; multi-radar antenna sequential rotation control can be achieved, and namely multiple radars needing coordination rotate in the manner that a certain included angle is kept between the radars needing coordination and the standard radar all the time and radars needing coordination rotates at basically identical speeds as the standard radar all the time; single-radar antenna final motion pointing control is achieved, and namely target extrapolated tracking information is provided for a single radar system in coordination to complete the function of tracking control on the target.

Description

Technical field: [0001] The present invention is a multi-radar antenna cooperative control method, which realizes synchronous rotation control of multiple radar antennas, sequential rotation control of multiple radar antennas, and micro-motion pointing control of a single radar antenna. This invention can greatly improve the frequency of radar detection targets, and is beneficial to Multiple radar backend data fusion. Background technique: [0002] At present, each radar station controls the rotation of the antenna in an independent manner.
