A novel waveform design method based on improved ambiguity function

Abstract

With the development of technology and the increase of people's demand, there are more and more intelligent requirements for radar. Intelligent radar should be more flexible, and transmits different waveforms according to different working conditions. In this paper, after analysis of point target echo, we propose an improved ambiguity function for uniform coherent pulse train signal (UCPTS), which can obtain more flexible waveform. In simulations, time frequency characteristics and ambiguity characteristics of the proposed waveform design method are provided. Simulations results demonstrate that the novel waveform design method for uniform coherent pulse train signal has good range and velocity resolution. Finally, a summary of the paper is presented.
