Shared aperture jamming

Webb29 okt. 2024 · Aperture sharing is fundamentally method of layout for designing antennas for multifunctionality of the antenna systems. It consists of a collection of elementary radiators that can be integrated simply or in antenna array configuration. In aperture sharing designs one can use identical radiators or different radiators using same surface. WebbSAR satellite has pulse compression gain through the process including range and azimuth. Efficient jammers against the SAR satellite with simulated elements were evaluated in the view of power and SAR image. In this paper, J/S is analyzed for SAR with RF propagation equation firstly. Several jamming signals against SAR signal were added …
