Abstract

This paper presents applications of a generalized theoretical analysis of Tsui´s phase measurement approach to detection of N - 1 ultraweak signals. A closed-form analytical expression is obtained for one application. A detection approach is presented for real-time estimation of the slope and curvature of sampled data of the instantaneous frequency. This approach provides the capability for early simultaneous signal detection and extraction of signal parameters. The capability for N = 4 simultaneous signals is desired for electronic warfare (EW) receivers.
