In the system-level design for both conventional radars and noise radars, a fundamental element is the use of waveforms suited to the particular application. In the military arena, low probability of intercept (LPI) and of exploitation (LPE) by the enemy are required, while in the civil context, the spectrum occupancy is a more and more important requirement, because of the growing request by non-radar applications; hence, a plurality of nearby radars may be obliged to transmit in the same band. All these requirements are satisfied by noise radar technology. After an overview of the main noise radar features and design problems, this paper summarizes recent developments in "tailoring" pseudo-random sequences plus a novel tailoring method aiming for an increase of detection performance whilst enabling to produce a (virtually) unlimited number of noise-like waveforms usable in different applications.
在传统雷达和噪声雷达的系统级设计中,一个基本要素是使用适合特定应用的波形。在军事领域,需要降低被敌方截获(LPI)和利用(LPE)的概率,而在民用领域,由于非雷达应用的需求不断增加,频谱占用成为越来越重要的要求;因此,多个相邻雷达可能不得不使用同一频段进行发射。噪声雷达技术满足了所有这些要求。在概述了主要的噪声雷达特性和设计问题之后,本文总结了“定制”伪随机序列的最新进展以及一种新颖的定制方法,该方法旨在提高检测性能,同时能够生成(几乎)无限数量的可用于不同应用的类噪声波形。
