| Abstract: |
| To address the challenges of high false alarm rates and difficulties in target identification in airborne reconnaissance and surveillance radar for maritime detection—caused by complex environmental conditions and diverse target characteristics—this study proposes an innovative integrated image-track fusion detection mode for maritime targets. Building on the detection capabilities of traditional airborne SAR (Synthetic Aperture Radar) and MTI (Moving Target Indication) modes, this approach integrates the advantages and compensates for the limitations of SAR and MTI through unified beam control, a sub-array digital antenna architecture, and adaptive frame rate selection. This enables simultaneous imaging and tracking of maritime targets, effectively resolving challenges in maritime target detection and identification. Starting from the core issues, this paper presents the design methodology for the integrated detection mode and analyzes experimental flight data. The results demonstrate that the proposed method significantly improves maritime target detection and identification performance under complex conditions. |
