Under the Strong Noise in Ultraviolet Missile Approach Warning to Extract the Target

In the ultraviolet missile approach warning signal processing, strong noise and burst interference will affect the test missile target, but the classic two-dimensional filtering algorithm cannot effectively filter out the interference, because the strong noise and burst interference and spatial location spatial frequency position is uncertain. This paper presents a three-dimensional image sequences filtering algorithm, the two-dimensional and one-dimensional spatial filter IIR filter composed of the time, the two filters are stable. This article also gives the stability detection algorithm. An advantage of three-dimensional recursive filter is a small amount of computation, and can achieve rapid real-time image sequences filtering. Ultraviolet missile approach warning signal processing simulation results show that three-dimensional filtering and related algorithms presented in this paper are correct, efficient and practical.
