摘要：

随着电子设备和雷达系统的迅速发展, 电磁环境变得愈加复杂。在复杂电磁环境中, 针对多辐射源和有源设备照射下雷达目标电磁散射特性评估的需求, 提出并综述了有源雷达散射截面(active radar cross section, ARCS)的定义、仿真方法和应用示例。ARCS可以计算多辐射源相干和非相干照射条件下, 雷达端观察到的视在雷达散射截面(radar cross section, RCS)值。本文给出了ARCS的仿真分析步骤, 利用仿真软件得出计算ARCS所需远场量。在单入射源情况下, ARCS等同于传统RCS, 验证了ARCS计算方法的准确性。此外, 以分布式相参雷达和有源对消目标隐身为例, 介绍了ARCS的应用, 利用ARCS的概念评估了有源对消的效果。最后, 探讨了目前研究存在的技术问题以及未来可能发展的研究方向。

Abstract:

With the rapid development of electronic devices and radar systems, the electromagnetic environment has become more complex.In order to evaluate the demand of electromagnetic scattering characteristics of radar targets illuminated by multiple radiators and active devices, this paper proposes the definition, simulation methods and sample application of active radar cross section active radar cross section (ARCS). ARCS can calculate the apparent radar cross section (RCS) value observed by radar under the conditions of coherent and incoherent illumination of multiple radiators. Here, the simulation procedures of ARCS are proposed.The far field quantity required to calculate ARCS is obtained by simulation software. In case of a single incident wave, ARCS is equivalent to traditional RCS which verifies the accuracy of the ARCS calculation method. Meanwhile, the applications of ARCS are introduced by distributed coherence radar and active echo cancellation. The ARCS concept is used to evaluate the effects of active echo cancellation. Finally, the technical problems existing in current research and possible future research directions are discussed.

Key words: active radar cross section (ARCS), coherent interference, radar stealth, active echo cancellation
