Paper Abstract

A narrowband signal excision system uses spatial light modulators in the spatial frequency domain to notch energy caused by narrowband interferers. We review the signal excision process and discuss the optical system developed to monitor the noise spectrum. A postdetection system searches for narrowband interferers in wideband spectra and provides control signals to implement the required notch; experimental results of the distortion imposed on short pulse signals are given.
