Abstract:

For interrupted sampling repeater jamming (ISRJ), this paper investigates the intra-pulse orthogonal working and protection waveform design method to suppress ISRJ. Considering the low Doppler sensitivity, the optimization problem is formulated by minimizing the weighted sum of the low Doppler sensitive and correlation function under the constraint of constant modulus. Since the problem involves a nonconvex fourth-order objective and a nonconvex constraint, it is difficult to obtain a closed-form solution. Therefore, a method based on cyclic algorithm is devised to solve the problem. Finally, compared with the existing waveform, the simulation results show that the designed waveform has low Doppler sensitivity and can counter ISRJ effectively.

Key words: low Doppler sensitivity, interrupted sampling, jamming countermeasure, waveform design, cyclic algorithm
