Final Report Abstract
The employment of a 2D-MIMO array in a radar enables the efficient estimation of the target position in a 3D space. To maximize the separability of a 2D array, while maintaining low sidelobe levels, an optimization of the array element positions is required. Thus, a general method for the evaluation of the performance of a 2D array based on the analysis of the ambiguity function is devised. Such a method is used as main criterion in a genetic algorithm for the optimization of 2D-MIMO arrays. The development of two demonstrators at 77 and 300 GHz proves the effectiveness of the optimization method. Moreover, the proposed approach allows the optimization of a 2D-MIMO array to be implemented in a single MMIC at 320 GHz. To this purpose, transmit and receive channels with integrated antennas are designed in two versions: with a vector modulator or an injection locked oscillator for phase shifting. Finally, for overall verification a multi-transceiver chip in the proposed sparse MIMO configuration is produced.
