Abstract
The narrowband signal revealer comprises a sensor, a baseband generator, an daptive locally optimum processor (ALOP), and a complex signal spectral analyzer. The sensor generates an input signal representative of a tonal signal masked by wideband interference. The baseband generator transforms the input signal into a complex baseband signal. The ALOP processes the complex baseband signal to suppress the interference and generates a complex output signal representative of the tonal signal. The spectral analyzer then analyzes the complex output signal and displays tonal signal power.
