Cognitive Optimization of Multitasking Detection for 2D E-Scan Airborne Surveillance Radar

This paper deals with detection optimization in the case of active electronically scanned array surveillance radar. The major advantage of electronically scan antennas compared to mechanical ones is the ability to interleave different processing. In coastal surveillance, this is a real advance because it is possible to detect maritime and ground target at the same time. A method based on cognition principle is presented here. The first step is to sense the environment and to extract characteristics which are not necessarily the same for sea and ground detection. Then, the proposed method aims to optimize the mode that would be the most suitable for performing a given task in each application ground and sea detection. The last step is to apply this optimization: it can be done by acting on a Software Defined Radar module.
