Study of Range Migration Compensation Method Based on Linear Regression

Abstract:

For Long-Term energy integration detection, we must conduct echo envelope compensation to correct all targets echo to the same range bin, through MTD or joint Time-Frequency transform complete energy accumulation. Keystone transform is an effective method for range migration compensation, but this algorithm is large amount of calculation against Real-Time processing. We present a method for range migration compensation based on analysis of linear regression, it makes use of the curve fitting for the processing of the migration compensation. We compare the two methods of computational efficiency, linear regression algorithm has better Real-Time process performance, and the effectiveness is conformed by the simulation results.
