摘要

本文介绍了一种采用pn码测距和波前重构进行角度识别的实验雷达的系统概念、设计和实现。通过对系统的道路评估，确定了径向和纵向分辨率、灵敏度和速度判别等关键系统参数的规格。仿真研究表明，通过选择合适的pn码参数，系统不受多普勒效应的影响。pn码的存储器读出概念能够快速访问径向分离的范围门，并允许在线跟踪多个对象。从评估过程中获得的关于测距、角分辨率和速度辨别的整体性能证明了这些原理的实用性，使其成为第二代自动巡航控制(ACC)或碰撞预警系统的潜在候选方案。

Spread spectrum ranging for an ACC-radar

The paper reports on the system concept, design and realization of an experimental radar using PN-codes for ranging and wavefront reconstruction for angular discrimination. The road evaluation of the system has confirmed the specifications regarding essential system parameters such as radial and longitudinal resolution, sensitivity and velocity discrimination. Simulative studies have shown that by choosing suitable parameters for the PN-code, the system is not limited by the influence of the Doppler effect. The memory readout concept for PN-codes enables the expected fast access to radially separated range gates and allows on-line tracking of several objects. The overall performance with respect to ranging, angular resolution and velocity discrimination obtained from an evaluation process demonstrates the usefulness of the principles, making them potential candidates for an implementation into second generation autonomous cruise control (ACC) or collision warning systems.
