Abstract :
This paper presents a novel application of mathematical morphology for Radar ELINT signals. The 1-D weak radar signals are transformed into 2-D time-frequency representation through the application of short-time Fourier Transforms (STFT). The time-frequency representation of these signals is treated as 2-D objects similar to images. Mathematical morphological operations are performed on this representation of the radar signals and are viewed as detectors. These Morphological detectors are found to be versatile in detecting weak radar signals.
