| 摘 要： | 为了解决脉冲压缩技术运用于超宽带（ultra-wideband，UWB）雷达系统中在增加其最远探测距离的同时也增加了探测盲区这一问题，提出一种利用长短脉冲相组合的伪随机（pseudo random noise, PRN）码调制的二相编码UWB信号作为雷达信号发射源，在满足短脉冲的最大探测距离大于长脉冲的最小探测盲区的条件下，解决UWB脉冲压缩雷达系统探测盲区的问题。Matlab仿真结果表明了理论分析的正确性及所提出的方法可以很大程度减小雷达探测盲区,说明所提出方法的可行性与优越性。

| 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. |
