A Heterogeneous Parallel Automatic Target Recognition Device for Ground-Fixed Targets on Moving Platforms

Abstract

The invention discloses a moving-platform heterogeneous parallel automatic identifier for geostationary targets. The identifier comprises a switched network and at least one processing part. The processing parts are connected with the switched network through input FIFO interfaces, synchronous storage output interfaces and control wires. The switched network is used for dynamically linking the different input FIFO interfaces and synchronous storage output interfaces. The processing parts are used for finishing various required algorithm functions during the process of automatic target identification. The input FIFO interfaces are used for caching input image data under processing. The synchronous storage output interfaces are used for caching processed image data under outputting. The control wires are used for controlling data transmission during the process of image data transmission. The uniform cache-bearing switched network is utilized, dynamic full interconnection among the different processing parts is guaranteed, resource consumption is reduced, and resource utilization efficiency of a system is improved.

Description

technical field [0001] The invention belongs to the technical field of digital signal processing, and more specifically relates to a heterogeneous parallel automatic target recognizer for fixed targets on the ground by a moving platform. Background technique [0002] Geostationary target imaging automatic target recognition belongs to the technology of target recognition in complex background. The ground background is very complex, and various complex structures such as streets, trees, buildings and different gray levels have caused great difficulties in target recognition. Moreover, various conditions such as the shadow of the target, the occlusion of the cloud layer, and whether it is backlit have a great impact on the recognition accuracy and stability of the target. Therefore, the algorithms employed in automatic target recognition for geostationary target imaging are particularly complex.
