Abstract :
To optimize thinned array pattern synthesis in multi-input multi-output radar, the distance perturbation is introduced and both transmit and receive antennas geometries are modified synchronously. Accordingly, pattern synthesis with a lower relative sidelobe level and maximum degrees of freedom are achieved.
