Individual Radio Frequency Interference Identification on VHF Radar Based on Time-Frequency and Chaotic Characteristics

Abstract

The radar reconnaissance plays an important role in modern electronic warfare as a critical link of radar countermeasures. We study individual radio frequency interference identification on the very high frequency (VHF) radar in the radar reconnaissance. The time-frequency and chaotic characteristics of the transient signals are extracted and based on these characteristics the tree classifier are designed. Real data experiments prove that individual radio frequency interference identification on VHF radar can be achieved through the method we propose .
