ABSTRACT This paper focuses on the design of synthetic aperture radar (SAR) deceptive jamming waveforms with spectral compatibility. We formulate an optimisation problem to minimise the matching error between the designed and the intercepted signal, under the constraint that the interference of the jammer to the nearby friendly radiators is controlled. Additionally, to enhance the effective radiated power of the jammers, we enforce a peak‐to‐average power ratio (PAPR) constraint on the waveforms. To deal with the formulated problem, we propose an iterative algorithm based on alternating direction multiplier method (ADMM). Numerical results demonstrate the fast convergence of the ADMM algorithm. Moreover, the jamming waveform designed by the algorithm exhibits high similarity to the waveform transmitted by the hostile radar. In addition, the waveform forms deep notches over the frequency band of the friendly radiator such that the interference is reduced. By using the synthesised jamming waveform, successful deception against the hostile SAR system is demonstrated by generating false targets with high fidelity in both range and azimuth.
