In order to investigate the influence of multi-radiators, active scattering characteristics, which can be reflected by the active radar cross section (ARCS), are investigated by incorporating the multi-radiators with the radar-radiator. The proposed implementation takes advantage of the ARCS concept in terms of considerable accuracy and close to reality especially in the complex electromagnetic environment. The metal sphere model is analyzed to demonstrate the effectiveness of the proposed implementation. Several procedures are employed during the investigation. The ARCS of the metal sphere model is compared with its radar cross section with a single radar-radiator. The frequency characteristic of the ARCS for a metal sphere model with multi-radiators is calculated. The changes in the ARCS with different phases, field intensities, field polarization directions are given. An example is given to illustrate the change in the maximum detection range caused by multi-radiators. Through the results, it can be concluded that the active scattering characteristics of the metal sphere model can be significantly influenced by the multi-radiators.

金属球模型的主动辐射多辐射器

为了研究多辐射器的影响，通过将多辐射器与雷达辐射器结合使用，研究了可以由主动雷达横截面（ARCS）反映的主动散射特性。所提出的实施方案在相当大的精度和接近现实的方面利用了ARCS概念，特别是在复杂的电磁环境中。对金属球模型进行了分析，以证明所提出的实施方案的有效性。在调查过程中采用了几种程序。将金属球模型的ARCS与单个雷达辐射器的雷达横截面进行比较。计算了具有多个辐射器的金属球模型的ARCS的频率特性。ARCS在不同阶段，场强，给出了磁场极化方向。举例说明了由多辐射器引起的最大检测范围的变化。通过结果，可以得出结论，多辐射器可以显着影响金属球模型的主动散射特性。
