Dimensionality Reduction Based on Radar Envelope Characteristics
Long Jian · Electronic Information Warfare Technology · 2011
Pulse envelope is an important feature of radar emitter.Traditionally,there is no better method to describe envelope features,especially the fine features brought by the unintentional modulation(UM) of radar system,and that leads to the application of pulse features to signal recognition is limited.Combining with the envelope fluctuation by UM and a variety of dimensionality reduction methods,the intrinsic dimension and low dimensional expression of envelope characteristics is discussed,so as to ensure the reliability of the feather and improve signal processing efficiency.
