Integrated sensing and jamming waveform design for range-velocity deception via hybrid intelligent optimization

The design of integrated sensing and jamming waveform (ISJW) aims to seamlessly unify radar sensing and electronic jamming functionalities within a single transmission framework. Although existing research has made progress in shared waveform construction and false-target generation, a unified framework remains elusive for achieving range–velocity (RV) deception while mitigating the sidelobe incoherence caused by velocity-induced pulse agility. To address these issues, this paper proposes an ISJW design method for RV deception via hybrid intelligent optimization. Specifically, a multi-dimensional modulation ISJW model is established, and the formation mechanism of two-dimensional false targets on the RV plane is analyzed. Furthermore, the pulse-agility period is derived from the slow-time phase evolution induced by relative velocities, and a joint mismatched filtering approach is introduced to recover sidelobe coherence. Subsequently, a constant-modulus multi-objective optimization problem is formulated to balance sidelobe suppression and inter-pulse similarity. To solve this, an integrated differential evolution and annealing (IDEA) algorithm is developed, incorporating a group-wise incremental synthesis mechanism to reduce computational overhead. Simulations demonstrate that the proposed method achieves RV deception for multiple false targets, effectively mitigates Doppler defocusing, and preserves sensing performance.
