Research of jamming signal's feature extraction of LFM pulse-compression radar

Abstract

Radar plays an important role in military communications. Jamming and antijamming are two basic tasks in radar signal processing. Masking jamming is a common class of radar jamming. Jammer releases noise or similar noise to cover or submerged useful signal to prevent radar detecting target information. For example, spot jamming through measuring the frequency of radar signal, then adjustment the jammer's frequency to radar signal to implement interference. Many researchers have studied kinds of new jamming forms. Paper combined shift-frequencyjamming and convolution jamming. © 2012 Springer-Verlag London Limited.
