title = "ECCM performance analysis of chaotic coded orthogonal frequency division multiplexing (COFDM) SAR",
abstract = "Conventional linear frequency modulation (LFM) synthetic aperture radar (SAR) is incapable of countering deceptive repeat jamming. In this paper, a new SAR signal based on chaotic coded orthogonal frequency division multiplexing (COFDM) is studied. The fact that chaotic codes are sensitive to the initial values allows generating a large number of different chaotic sequences to form SAR transmitting waveforms, where all the signal sequences are orthogonal to each other, enabling COFDM-SAR countering not only active noise but also deceptive repeat jamming. The procedures for COFDM waveform generation and SAR anti-jamming processing are discussed. Comparative studies of the electronic counter-countermeasure performance (ECCM) between COFDM-SAR and conventional LFM-SAR are made. Simulation results are presented to demonstrate the superior performance of COFDM-SAR in countering repeat deception as well as active noise jamming.",
