Coordinated multi-beam target search method in the whole space

Abstract

The invention discloses an all-space multi-beam cooperative target search method, aiming to provide a method capable of effectively covering the whole space and quickly searching the whole space. The present invention is realized through the following technical solutions: in the search phase, the target search module controls the receiving beams generated by the antennas, cooperates to complete the initial target search, enters the low elevation angle monitoring phase, and the target search module controls the multi-beam resources of the measurement and control communication system, for Cooperative search is carried out in the area of ​​elevation angle, and the information parameters of the discovered target are sent to the new target judgment module; the new target judgment module matches and compares with the existing target information in the dynamic target library module according to the target information parameters sent by the target search module , if the matching fails, send the target information sent by the target search module to the beam tracking module, control the measurement and control communication system to track the new target, and update the target information in the dynamic target library module in real time according to the target information obtained by tracking the target Target information parameter.

Description

technical field [0001] The invention relates to an all-airspace multi-beam cooperative search method which is mainly used in the field of aerospace measurement and control communication and can be applied in the field of situational awareness. Background technique [0002] Aiming at the growing demand for multi-satellite simultaneous measurement and control, the present invention provides an array antenna target search technology for simultaneous measurement and control of multiple beams in the whole space. Digital multi-beam antenna reception means that the measurement and control communication system selects the active array elements and controls their complex weights to perform beamforming according to the beam pointing information, and completes the signal reception in the predetermined direction, and the area that does not participate in the beamforming area closes the channel. Multiple beam signals form composite signals pointing in different directions under the contr...
