Since many target characteristics can be extracted from the echoes by wideband inverse synthetic aperture radar (ISAR), the jamming signal on ISAR need to simulate the electromagnetic scattering characteristics and kinematics characteristics with high fidelity. According to the electromagnetic scattering mechanism of missile target, the generation process of jamming signal was analyzed and a scheme for two-dimensional imaging jamming was proposed. Concerning the false target characteristic simulation issues, an algorithm was presented, using high range resolution profile (HRRP) template to synthesize a deception jamming signal via convolution operation with actual ISAR signal. By multiple pulses simulations, the obtained jamming signal is capable of simulating the electromagnetic and kinematic characteristics accurately. In numerical experiments, the imaging results were compared by using dark room measurements and HRRP template data, and it verified the effectiveness of the proposed algorithm, which has guiding significance for the engineering design of two-dimensional imaging jammer.
