A set of features for classification of intrapulse modulations
Kenan Gençol · 2016
In modern electronic warfare environments radar emitters intentionally modify their pulse repetition intervals and intra-pulse parameters in specific patterns called modulation. While pulse repetition interval modulation serves for a hidden functional purpose of the emitter, intra-pulse modulation also known as pulse compression techniques makes it possible to simultaneously maximize the target range and the range resolution of a radar. In this study, new features due to automatic recognition of intra-pulse modulations are proposed. These features are extracted from the amplitude histograms of radar signals. Experimental work shows that common modulation types can be highly separated by the utilization of the proposed feature set.
