摘要

本文研究了用匹配分数傅里叶变换(FRFT)对啁啾脉冲进行分析和处理。利用频响傅立叶变换和模糊函数的特性，系统地推导了基于匹配频响傅立叶变换的啁啾脉冲的时延和多普勒频移的分辨性能。本文还提出了利用匹配的频域变换抑制旁瓣的方法。仿真结果验证了理论推导的正确性。

Analysis and Processing for Chirp Pulse with Matched FRFT

In this paper, we consider analysis and processing of chirp pulses using the matched fractional Fourier transform (FRFT). Using the properties of the FRFT and the ambiguity function, the resolution performances of time delay and Doppler shift for chirp pulses based on the matched FRFT are derived systematically. The method for sidelobe suppression using the matched FRFT is also proposed. Simulation results are presented for testifying the theoretical derivations.
