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

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.
