Radar seekers for air targets - research issues

The report contains a proposal for a collected research effort concerning radar seekers for air targets, especially at medium to long distance, an area with no substantial Swedish activity for some time. The aim is to develop better methods for target state determination by joining competence at the FOI (Swedish Defence Research Agency) in theoretical analysis, measurement, simulation and verification, with foreseen collaboration with Swedish universities and industry. The report contains a short overview of relevant system aspects, with some references to unclassified seeker related ongoing research within and outside the FOI. A proposal is made for a general direction of the research aiming at finding new or improved methods for - recognition or classification of targets - estimation of target trajectory, state and aimpoint - detection of target manoeuvers - estimation of passage geometry
