Impact Analysis of Passive Multi- False Targets to Phased Array Radar Resources

The phase-switched screen (PSS) can change the reflected echo of the target through a certain control method, thereby generating false targets. The study of material properties and the impact of materials on radar has attracted a lot of attention from the academic community. However, there are few studies on the influence of signal echo changes caused by artificial surface metamaterials on radar resources. In this paper, using PSS to change radar echo information to generate false targets in the Doppler frequency domain. Then the multi-false targets jamming effect on radar resources and multi-target tracking is analyzed. Simulation results show that these targets can consume radar search and tracking resources, generate a large number of temporary trails. This research is beneficial to the application of PSS for interference radar resources.
