Research on methods to enhance the survivability of AWACS with FDA against anti-ARMs on a battlefield

Abstract

The Airborne Warning and Control System (AWACS) are pivotal assets in aerial operations, necessitating specialised protection measures, and serving as prime targets for enemy anti-radiation missiles (ARMs). This paper explores approaches to enhance the battlefield survivability of frequency diverse array AWACS (FDA-AWACS) by incorporating airborne radar technology onto the platform. The study commences by analysing the typical operational methods of anti-radiation missiles. Following this, a deception model is formulated for the frequency diverse array (FDA) against the passive radar homing head of anti-radiation missiles utilising the adjacent antenna single-pulse amplitude-comparison direction-finding technique. Expanding on this groundwork, the research further assesses the deceptive impacts of FDA-AWACS on direction finding cross-location techniques. Simulation results validate that FDA-AWACS can effectively counter the threat of anti-radiation missiles by diminishing their direction-finding and positioning systems.
