Abstract

The invention discloses a multichannel measurement information configuration method based on space grid data alignment. The method is characterized by carrying out space grid division on a space monitoring space, calculating pitching-orientation-distance information of each space grid corresponding to each radar by utilizing geometrical relationship between space grids and radars, recording mark numbers of the grids and establishing a grid retrieval matrix; then, determining a scanning irradiation mode of a wave beam, and enabling the grid retrieval matrix to be in one-to-one correspondence with the irradiation modes to obtain a two-dimensional grid-mode retrieval matrix; and finally, mapping the pitching-orientation-distance information of the space grids into a local grid information data retrieve table based on mode mark numbers, extracting a detection unit corresponding to each grid according to the grid data table and serving measurement accumulation corresponding to each channel detection unit as detection statistics amount and carrying out detection on a monitoring plane.

Description

technical field [0001] The invention belongs to the technical field of radar target detection, and in particular relates to a multi-site distributed network radar signal level joint target detection technology. Background technique [0002] With the development of science and technology, stealth aircraft, stealth drones, cruise missiles and other stealth targets have a small back-scattering cross-section, which greatly challenges the modern air defense network system. In order to deal with the threat of stealth targets, a distributed multi-node network radar is adopted. The system, through the use of space diversity, frequency diversity, polarization diversity and other technologies in different dimensions, can effectively overcome the problem of difficult detection of stealth targets based on backscattering characteristics. At this stage, the use of distributed network radar technology to detect stealth and other targets is still at the stage of theoretical exploration, and...
