Abstract:

Cooperation in multiple-radar has become an important trend in radar deception electronic counter-countermeasure. To solve the problem that the existing signal fusion-based methods cannot achieve a constant false alarm rate, this paper proposes a novel target discrimination method based on the difference in amplitude ratio feature. By the analysis of the random distribution of target amplitude ratio, multiple-dimensional test threshold is applied to discriminate the detected targets under a preset false alarm probability. Simulation results verify the feasibility and effectiveness of the proposed method.

Key words: multiple-radar system, deception jamming, amplitude ratio feature, active false targets discrimination
