Abstract
This paper presents a generalized theoretical analysis of Tsui's phase measurement approach for the situation in which there are N simultaneous signals, where one of the signals is strong and N - 1 signals are weak. Signal amplitudes are normalized to the amplitude of the strongest signal. This approach provides the capability to extract values of the signal parameters. The capability for up to N = 4 simultaneous signals is desired in the design goal for electronic warfare receivers.
