Abstract :
Performance of maximum entropy (ME) processing in the space-angle domain is analyzed. The effects on the ME images of phase differences between coherent sources, observed in simulation results, are explained. The effect of noise on the resolution of incoherent sources is analyzed. It is shown theoretically that the minimum required signal-to-noise power ratio at the output of the array is proportional to the inverse cube of the desired resolution.
