Investigation of Chirp Stepped Signal Performance for 60GHz Millimeter Wave Radar

Abstract

The performance of the chirp stepped signal (CSS) is investigated in this paper. Based on the ambiguity function theory, a 60GHz radar system performance with CSS, such as, distance, speed and angle detection are firstly analyzed and then simulated and experimental verified. Finally, using our designed CSS, a higher signal-to-noise ratio (SNR) and improved range detection capability are obtained under the condition of low instantaneous bandwidth when compared with the FMCW signal. Our results show that the CSS has a good potential for 60GHz millimeter radar applications.
