Radar target high range resolution profile splicing is a premise for the application of one-dimensional high range resolution profile in radar target recognition. The velocity of moving target will produce cyclic shift of the range profile, which may cause losing target on range profile with traditional redundancy removement algorithms like discard method or method of selecting the large with same distance. The influence of target motion on high range resolution profile of stepped frequency radar is analyzed, while cyclic shift discard profile splicing algorithm which avoids extracting loss is proposed. The algorithm makes selected range move with range profile by modifying the pick-up scope based on the offset of the most powerful scatterer, which overcomes the effects of target motion on traditional range profile splicing algorithm while avoiding large computation of accurate motion compensation, thus showing engineering application value. Computer simulation validates the correctness of theoretical analysis. [ABSTRACT FROM AUTHOR] |
