Recognition of Warhead by Range-Profile Matching
Donglin Tan, Junfeng Wang · 2021
A novel algorithm is presented for warhead recognition in the defense of ballistic missiles. The deviation of a range profile from a standard range profile is measured by the 2-norm of the difference between the two range profiles. A target is recognized as a warhead if the deviation of its range profile from the range profile of the warhead is less than a threshold. The threshold is chosen such that the detection rate is constant. Since the threshold is automatically calculated according to the signal- to- noise ratio and the detection rate, this algorithm has a larger applicability than the traditional methods based on range-profile matching.
