On deception jamming for countering bistatic ISAR based on sub‐Nyquist sampling

Abstract

Bistatic inverse synthetic aperture radar (ISAR) operates with spatially separated transmitting and receiving antennas. This study presents a method capable of generating deceptive images from a series of intercepted bistatic ISAR chirp pulses. It is demonstrated that deceptive false‐target images will be induced by the under‐sampled pulses which are retransmitted to a moving target and scattered by it under the principles of bistatic ISAR configuration. Additionally, the jamming idea is proved to be applicable based on the characteristics of the false‐target images and the requirement of jamming power. A scattering model of Yak‐42 plane with 330 point scatterers is adopted to verify the effectiveness of the jamming idea.
