DETECTION OF SMALL QUICK TARGETS BY NON-COHERENT POST-INTEGRATION USING A SLIDING CLASSIFICATION ALGORITHM

摘要

The invention relates to a method for non-coherent integration and detection applied to data received during two consecutive scans of a predetermined area of space by a detection system, such as a radar, entrusted with observing the area. The inventive method comprises cutting the space in question into analysis cells and measuring the power received in each one of the cells over two consecutive scans. The method next comprises determining for each cell m a neighbourhood v_m made up of juxtaposed cells located in an area with predetermined dimensions surrounding the cell in question. The invention finally comprises successively calculating for each cell m the sum of the energy measured in said cell during a predetermined scan n+1 and the energy measured during the previous scan n in each one of the L cells of the neighbourhood v_m which have the L highest measured energy values, and then comparing each result with a threshold T. Henceforth, a detection is carried out for the cell m every time a result exceeds the threshold T. The L cells to be considered are defined by implementing a specific algorithm suitable for limiting the calculation load produced by said operation.
