Radar Model Development

摘要

The present invention provides a methodology to develop a simulation model of an existing array radar 1 with multiple transmitters and receivers, and accurately simulate radar performance without access to the actual radar CAD data.In particular, reverse engineering technique has been applied to accurately capture the geometry details of each individual transmitter and receiver array elements 2.Initially, the radar transmitter and receiver dimensions are estimated based on measurements of actual radar components.By applying an optimization technique, the geometry details of each individual transmitter or receiver array elements 2 and substrate 3 are determined by maximizing the power of the main lobe and by minimizing the noise level of side lobes of the radiation pattern.Similarly, to further improve the accuracy of the radiation pattern of the radar model, an optimization technique is applied to determine the magnitude and phase of excitation for each individual array element 2.The radiation pattern of the radar model developed using the proposed approach shows good agreement with the radiation pattern of the actual radar.
