摘要
蒙皮阵面与飞行器表面共形,可以实现全向目标探测。针对飞行器蒙皮阵面成千上万的阵元,基于天线方向图综合和子阵分割的阵面资源分配算法无法实时应对复杂多变的战场环境。本文利用等效全向辐射功率衡量目标探测所需的射频资源,采用阵面投影的方法将复杂的三维蒙皮阵面投影到二维球面,并通过顺序特征匹配方法判断多目标探测时是否存在共用阵面的情形。本文以西科斯基S-97“突袭者”直升机为试验对象进行仿真试验,仿真试验表明所提方案能够有效分配蒙皮阵面资源探测侧面和仰视目标,判断阵面资源调度重叠情况,可应用于多目标探测时采取时分复用工作模式的蒙皮阵面孔径资源预分配。
The conformal integration of aircraft skin array radar with the aircraft surface enables omnidirectional target detection.Due to the thousands of elements in the skin array,array allocation algorithms based on antenna pattern synthesis and subarray segmentation are unable to respond in real-time to the complex and dynamic battlefield environment.This paper employs the effective isotropic radiated power to quantify the required RF resources for target detection and utilizes the array surface projection method to project the intricate three-dimensional skin array onto a two-dimensional spherical surface.Additionally,whether there is array sharing during multi-target detection is judged through a sequential feature matching method.The experimental subject in this paper is the Sikorsky S-97 Raider helicopter.Simulation experiments indicate that the proposed approach can effectively allocate skin array resources for detecting side and elevated targets,and determine the existence of array overlap.The proposed approach can be applied to the pre-allocation of skin array aperture resources in a time-division multiplexing mode during multi-target detection.
