Abstract. The effects are investigated of solar heat irregularity on shape distortion of grid reflector used as a calibration object for RADAR means testing. The proposed approach to the problem is based on application of finite element method. Results of numerical study are presented.
Keywords: RADAR calibration, irregular heating, shape distortion, spherical grid reflector, effective scattering area.
