Research on Anti-Jamming for Vehicle Millimeter Wave Radar Based on Frequency Hopping Technology

Abstract

To address the interference issues among vehicle millimeter wave radars, this chapter proposes an anti-jamming technique that involves frequency hopping of the signal at the transmitter side. By varying the frequency of the radar transmission signal and based on different frequency hopping sequences, it is possible to distinguish between the transmission signal and interference signals, thereby achieving the purpose of interference suppression. This study validates the anti-jamming performance of the proposed solution under different interference conditions through theoretical analysis and simulation. The simulation results indicate that the scheme can effectively suppress interference in scenarios with both single and multiple targets, enhancing the system's stability and reliability.
