A new algorithm for recognizing and estimating radar signal parameters

Abstract

This paper proposes a new algorithm based on image processing to recognize and estimate radar signal parameters such as carrier frequency, pulse width and modulation. The algorithm includes three steps. In the first step, banking filters are used for detecting and estimating signal carrier frequency. Time-frequency analysis is used in second step to extract signal feature. The last step is based on image processing for estimating pulse width and signal modulation. The simulated signals in MATLAB is used to evaluate performace of algorithm. Simulation results show that the proposed method is able to recognize and estimate parameter of single and multi-component signals.
