Improving Array Manifold Performance in Direction Finding Multi-Bay Antennas via Bay Spacing Optimization
Year: 2024
Type: article
Abstract: This paper proposes a method to minimize the mutual interference between elements operating in different frequency bands in a multi-bay array antenna for wideband direction finding systems by optimizing the spacing between bays. Array antenna manifolds in practical environments often deviate from the ideal manifold obtained via mathematical modeling because factors such as mutual coupling, mechanical structure, and surrounding environmental conditions. The proposed method facilitates the optimization of the bay spacing to minimize the impact of these factors on the array manifold, thereby improving the direction finding accuracy. Experimental results demonstrate that the proposed method effectively improves the array manifold measurement and enhances direction finding performance. This technology holds strong potential for broad applications in various civil and defense fields requiring signal detection capabilities.
