Abstract
A deception jamming method for wideband linear frequency modulation radar based on time-modulated array (TMA) is proposed in this letter. Different from other real-time modulation jamming methods using metasurface, the real-time modulated method based on TMA, where the system consists of discreet components of passive antenna, low-noise amplifier (LNA), analogy switches etc., shows merits of wide system bandwidth and extra gain for false targets. Hence, in view of the TMA-based method, this letter establishes the real and false targets’ amplitude model under nonuniform and uniform modulation. The situation of switches’ opening instant linearly varying with antenna order is introduced to manipulate false targets’ energy distribution in both observed angle and range directions. Numerical simulations are conducted to discuss the false-target characteristics under different modulation parameters. In the experiment, a two-element wideband jamming system covering 6 GHz to 18 GHz is constructed to demonstrate the proposed method's feasibility.
期刊介绍：
IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
