摘要

传统的雷达高度计系统，如脉冲或调频连续波(FM CW)在测量范围和安全性方面存在局限性。本文提出了一种基于直接序列扩频(DSSS)的雷达高度计，该高度计具有良好的分辨率和低截获概率。我们对系统进行了MATLAB仿真，并用缩小的原型模型验证了结果。计算了系统的各种性能指标，包括误码率(BER)，并与理论结果进行了比较。

Design and Implementation of a Spread Spectrum Based Radar Altimeter

Conventional radar altimeter systems such as Pulsed or Frequency modulated continuous wave (FM CW) have limitations on measurable range and security. In this paper, we propose a Direct sequence spread spectrum (DSSS) based radar altimeter that offers good resolution and low probability of intercept. We carried out MATLAB simulations of the system and verified the results with a scaled down prototype model. Various system performance measures including Bit error rate (BER) were computed and compared with the theoretical results.
