In this study, an algorithm for chain coverage model is proposed. The proposed algorithm is in
accordance with existing out-of-database target rejection techniques in radar target recognition Using High
Range Resolution Profiles (HRRP). This algorithm arranges the target samples in order based on the changes
of elevation angles to construct a sausage-like coverage area for every two neighboring samples. Then the
chain-like coverage model is constructed by connecting each area in proper order. This model depicts a
complicated boundary structure of target samples distribution in a high-dimensional space. In this case, each
kind of target constructs its own compact coverage area. The judgment with acceptance or rejection is that in
terms of test samples whether or not within the target coverage area. If the test sample is accepted by several
targets simultaneously, a generalized membership function is put forward to evaluate the strong or weak degree
of acceptance samples subject to certain target and realize target identification. The experimental results
demonstrate the effectiveness of the algorithm.
