| Abstract(in English) | A lot of attention has been paid to DS-UWB(Direct Sequence-UWB) radar. It can measure the distance to the target with high precision. In order to prevent a collusion, it is required for the vehicle radar to measure the distance in short time. The conventional radar has the problem that we need to change the length of spreading codes timely because we don't know the distance to the target. In this paper, we propose a novel DS-UWB radar based on parallel transmission system. This radar makes it possible to measure various distances by plural codes having different lengths. As a result, we can shorten ranging time. In addition, we introduce orthogonal pulses into our proposed radar system in order to reduce the interference between simultaneously transmitted signals. The improvment achieved by these orthogonal pulses has been shown in this paper. |
