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

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.
