Embodiment Construction

[0036] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0037] The present invention provides a MIMO radar preference optimal layout method under multiple monitoring areas, such as figure 1 shown, including the following steps:

[0038] S1. Determine a reference point according to preference information.

[0039] Distributed MIMO radar simultaneously monitors M monitoring areas within a given station layout area, and determines a reference point in combination with given preference information The value of the reference point is our expected monitoring performance value, where v i is the expected objective function value of the i-th monitoring area, that is, it is hoped that through site layout optimization, the monitoring performance of the monitoring area can reach the value of the reference point or approach the reference point. The objective function f(Θ) is related to the radar station location Θ.

Abstract

The invention discloses an MIMO (Multiple-Input Multiple-Output) radar preference optimization netting method in a multi-surveillance area. Firstly, a surveillance area and a netting area are determined, an objective function is determined, and a reference point is set according to preference information; then, with the reference point as the guide, a particle swarm optimization algorithm based on preference is used for reasonably optimizing an antenna netting position; and finally, from outputted netting schemes, a netting method closest to the reference point is selected for reasonable radar netting. The surveillance performance of a preference surveillance area can be enhanced, and more radar optimization netting methods can be acquired.

Description

technical field [0001] The invention belongs to the technical field of multi-input multi-output radar station layout, and in particular relates to the design of a MIMO radar preference optimization method for station deployment under multiple monitoring areas. Background technique [0002] The Multi-Input Multi-Output (MIMO) radar networking system uses the observation and judgment of multiple radars whose spatial positions are separated from each other and their coverage areas overlap each other to search, track, and identify targets in the surveillance area. Reasonable deployment of radar network can make a qualitative leap in the radar system's ability to monitor the surveillance area. Therefore, it is extremely important to study the optimal location of the radar antenna. [0003] For the research on the optimal deployment of MIMO radar, domestic and foreign research institutions have proposed many solutions. For example, A.M.Haimovich proposes a continuous exhaustive ...
