Ranging for Stepped-FM Coded Radar

摘要

The stepped-FM coded radar realizes a radar profile with excellent freedom from radar mutual interference and high resolution by using the inverse discrete Fourier trans- form (IDFT) of a part of the broadband transmitted signal and the narrow-band baseband signal obtained by ho- modyne detection. However, if the automotive radar fre- quency is increased beyond 60 GHz, a large measurement error occurs even for targets with small relative speed.
