摘要

摘要: 該文利用基于并行核外高階矩量法的區(qū)域分解法(DDM)快速準(zhǔn)確地分析了機(jī)載雷達(dá)相控陣的受擾特性。分析機(jī)載相控陣主波束相位掃描變化時，可將其分為機(jī)載平臺和相控陣兩個區(qū)域。由于機(jī)載平臺不變，故在求解過程中只需計算一次，并利用核外技術(shù)將該部分的阻抗矩陣等相關(guān)數(shù)據(jù)信息存入硬盤。每改變一次掃描角，只需重新計算相控陣區(qū)域，進(jìn)而結(jié)合已存儲的機(jī)載平臺區(qū)域，通過迭代便能得到機(jī)載相控陣的受擾特性。該方法能夠大幅度降低大型機(jī)載問題的計算時間和存儲需求。數(shù)值仿真實例表明，該方法可用于高效分析大型機(jī)載平臺中的雷達(dá)相控陣天線布局問題。

Abstract: A parallel higher-order and out-of-core based Domain Decomposition Method (DDM) is proposed for analyzing the disturbed characteristics of large airborne phased radar antenna array. When the phase of main beam sweeps for the airborne phased radar antenna array, the problem is divided into two parts: radar antenna array and airborne platform. The platform which remains unchanged during the overall solution is simulated only once at the beginning, and then the relative data, such as impedance matrixes are written into hard disk using out-of-core technique. When the phase sweeps, only the phased antenna array part is concerned. Finally, the accurate results are obtained by iterative solution. This method largely reduces the CPU time and storage requirements. The numerical example demonstrates that the proposed method is very suitable for analyzing the layout of large airborne phased radar antenna array.
