Imaging radar progresses as TRINA scientists contribute optimization methods for planar array antenna structures.
Increasing the capability of radar sensors on vehicle is important for the next generation of safety systems. Advances in radar include imaging radar, which enables the formation of three-dimensional point clouds of scanned areas surrounding the vehicle. A challenge in developing imaging radar relates to the complexity of designing a much larger array antenna that comprises numerous array elements. TRINA’s Electronics Research Department has proposed an optimization strategy using gradient-based non-linear programming in the article ‘Optimization of Planar Phased Arrays for Vehicles.’ The method was further exploited to analyze and assist in the design of an array antenna as reported in the paper, ‘Thinned Array with Steerable Nulls to cancel Grating Lobe for Automotive Radar Applications,’ which was presented at the 52nd European Microwave Conference (EuMC).
