Abstract

A short penetrating distance is a drawback of traditional ultra wideband radar systems. A pulse compression technique has been used in UWB radar systems to increase the penetrating distance. However, this leads to an increase in the blind zone. The paper proposes a new method to address this issue which uses combined binary phase-coded UWB signals that are pulse-modulated by a pseudo random number (PRN). We demonstrate that this method does not cause an increase in the blind zone as long as the maximum detection range of the short pulses is longer than the minimum detection blind zone of the long pulses. The simulation results show that the theoretical analysis is correct and the proposed method can greatly decrease the radar detection blind zone. Furthermore, we demonstrate the feasibility and superiority of the proposed method in improving the performance of radar detection systems.
