Balancing Antenna Performance vs. Radar Cross Section for a Passive Radar-Detecting Sensor on an Aircraft

In this paper, we have discussed and summarized the techniques of radar cross section reduction (RCSR). RCSR has been prompted due to the evolution of military technology. The paper reviews the basic concepts and characteristics of metamaterials, as these are the most favorable development that impacts defense industry products and stealth technology. This paper emphasizes the role of airpower and the ever-increasing demand for stealth. Initially, the blending of the fundamental aspects of stealth technology through radar signatures and methods of signature reduction are discussed. Then, the description of metamaterials and detailed analysis of their properties is made. This paper review the fundamental properties of metamaterials. It also explores the recent research activities on metamaterials in various areas. Some existing researches techniques used for RCSR are examined. The metamaterials are engineered media whose electromagnetic responses are different from those of their constituent components. The general benefits of metamaterials are pointed out in the paper. Metamaterials are mostly used in antenna configuration for enhancing antenna performance such as realizing miniaturization, expanding the operating band, enhancing gain as well as reducing RCS. These characteristics of the metamaterials are basically the reason why metamaterials should be used in stealth technology. The various categories of metamaterials used for RCSR are studied in the paper. In this paper, we have also proposed a unit cell. The unit cell consists of a square loop and intersecting strips at the edges of add shaped structure.

Fluctuation Model

The paper presents the issues related to the probability of surface objects detection. The classical fluctuation models and the new fluctuation model for small floating objects with 10 m2 radar cross section surface are described. The possibilities of detection of examined passive radar reflectors by the radars on board merchant vessels were determined. Probability of detection of passive radar reflectors calculated using the classical fluctuation models was compared with the results obtained using the proposed new fluctuation model.

Antenna Performance

This paper presents an electromagnetic wave absorbing technique to reduce a radar cross-section (RCS) of a patch array antenna without compromising their antenna performance. The technique is based on periodic patterns, which is made of resistive materials. The 2×2 patch array antenna with a resonance frequency of 3.0 GHz was designed and fabricated. To reduce the RCS of the patch array antenna, the periodic patterns using a square patch element were proposed and applied to the surface between the four antenna patches. The printed lossy periodic patterns have radar absorbing performance at 12.0 GHz frequency. The measured results show that the lossy periodic patterns have no significant effect on the antenna radiation performance. On the other hand, the RCS is reduced by more than 98% compared to the conventional antenna at the target frequency.
