An improved model of vehicle radar for multi-target based on stepped frequency pulse radar

The vehicle radars should be able to detect all stationary or moving objects inside the observation area with short measurement time, high range and velocity resolution, and cost efficiency. To achieve this, an improved model called Double-SFPW based on SFPW is described, it transmits two stepped frequency pulses with a frequency shift and a time difference, its performance is better than conventional LFMCW radar on multi-targets with a shorter measurement time, higher resolution, and solves the Doppler shift and frequency spread over of SFPW, in addition, Double-SFPW has a simple structure based on pulse radar, so it´s also very cost efficient.
