Experimental Study on Multiantenna Interference Technology

In this article, the multiantenna synthetic false target electromagnetic interference technology is discussed, which is a kind of glint electromagnetic interference technology. The phase wavefront of any angle distortion can be flexibly synthesized by adjusting the feeding amplitude and phase value of the interference system to complete the interference to the radar. The experimental verification of multiantenna interference technology is completed, which is based on the mathematical theory of multiantenna interference technology and the theory of equivalent radiation centers. The experimental target is set and the experimental scheme is designed, and the experimental test is completed through the final physical experimental model, which is based on the numerical calculation and electromagnetic simulation results. The feasibility of the multiantenna interference technology is verified successfully based on the experimental physical test means and experimental analysis conclusion, which verifies that the multiantenna interference technology can complete the interference at any position in the 2-D plane. The test results show that the triplet system can synthesize the position of the false target beyond five times the baseline length of the jamming antennas from the platform center when the jamming distance is 10 m and the baseline length of the jamming antennas is 0.2 m. Then, it has the wide phase parameter tolerance of 0°±20°, 120°±20°, and 240°±20°.
