摘要
Abstract
In radar target recognition based on high resolution range profile , power transform is a common nonlinear preprocessing method, which can improve the recognition rate .But the performance of high resolution range profile target recognition with power transform is seriously affected by signal-to-noise ratio, and the recognition result is significantly affected by the choice of the power transform exponential , even the effect is adverse .In this paper , logarithm transform is raised for high resolution range profile pre-processing to solve the problems of power transform , and a comparative analysis of the similarities and differences between the mechanism of logarithm transform and power transform is provided , and the impact of logarithm transform on the intra-class and in-ter-class correlation coefficients of high resolution range profiles is analyzed .The results show that logarithm transform is more suit-able for high resolution range profile preprocessing than power transform , and the experimental results based on measured data show that logarithm transform can more effectively improve the recognition rate than power transform .关键词
