A method of joint high-precision estimation of range and velocity in a radar using ultra-wideband frequency coded waveforms

Abstract

The article describes a method of joint high-precision estimation of range and velocity in ultra-wideband short-range radar systems. The peculiarity of the method is the two dimensional range-velocity compression function based on ambiguity function of ultra-wideband discrete frequency coded waveforms. Expressions of ambiguity function and compression function such as a block diagram of the radar transceiver for the proposed method are presented. Experimental data confirm the efficiency of the method.
