Abstract:

The technology of pulse compression is used in the ultra-wideband (UWB) radar system to increase the detection capabilities. However, the blind zone is augmented at the same time. Binary phase-coded UWB signal which is modulated by the pseudo random noise (PRN) code is used as the novel combined pulses. When the maximum detection range of the short pulses is longer than the blind zone of the long pulses, it could be used to solve the problem of the rising blind zone in the UWB pulse compression radar system. The results simulated by the Matlab show that the theoretical analysis is correct and the proposed method can greatly decrease the radar detection blind zone. This shows feasibility and superiority of the proposed method.
