A calibration method for a high-resolution hybrid MIMO turntable radar imaging system is presented. A line of small metal spheres is employed as a test pattern in the calibration process to measure the position shift caused by undesired antenna effects. The unwanted effects in the antenna near-field responses are analysed. modelled and significantly mitigated based on the symmetry and... https://fitnessgravesyardes.shop/product-category/hr-grip-kit/
