摘要：
Long range radars against automotive collisions are of interest in order to increase the road traffic safety. In this paper we present an approach based on the classic direct sequence spread spectrum method, where the pseudo noise sequences consist of gold codes or chaotic signals. By exploiting the degrees of freedom they offer, in conjunction with their good correlation properties, chaotic signals are potentially able to improve the system efficiency compared with gold codes, by increasing the radar detection capability. Numerical examples are provided in a simplified scenario.
