Pre-Allocation of Skin Array Resource Based on 3D Shape Projection
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.
