A synthetic aperture radar (SAR) is a system that uses moving radars to form images. SAR is widely employed, often utilizing satellites as platforms, and has a significantly high utility, especially for military purposes. It exhibits notable advantages in target detection and identification with the added benefit of minimal constraints related to time and weather. Therefore, research on SAR jamming is crucial. Conventional SAR jamming techniques can be categorized into noise and deceptive jamming. Noise jamming involves transmitting noise signals to lower the signal-to-noise ratio (SNR) of SAR images. Noise jamming spreads across the entire image, resulting in poor energy efficiency. In contrast, deception jamming does not reveal the presence of a jammer and allows the manipulation of the SAR image. However, the technological requirements of deception jamming are currently challenging for practical applications. In this study, we propose a SAR jamming technique using a single-frequency sinusoidal waveform. The proposed method reduces the utility of the SAR images by generating rectangular blocks within the images. Moreover, the proposed method can easily generate transmission signals and offers excellent power efficiency. [ABSTRACT FROM AUTHOR] |
