Optimization of False Target Type Jamming Against CA-CFAR Utilizing Radars

In this paper, the multiple false target jamming technique applied against radars using the Cell Averaging Constant False Alarm Rate (CA-CFAR) algorithm has been analyzed. The aim of the multiple false target technique is to ensure the detection of the highest number of false targets in the threat radar. Parameters related to the CA-CFAR algorithm directly affect the success rate of real target detection for the radar, and also play a decisive role in detection performance under jamming. In the jamming technique aiming to produce multiple false target, the pulse to pulse interval (gap) and pulse width (PW) are design parameters. In this study, through simulation, the jamming parameters that provide the maximum number of false targets that can be created using the multiple false target technique in radar receivers with different CA-CFAR parameters have been obtained. Based on the simulation results, using linear regression, a linear model representing the relationship between jamming parameters (PW and gap) and CA-CFAR parameters are obtained and presented as a rule of thumb for jamming parameter selection.
