| Abstract: |
| To achieve robust and early warning of incoming dense hypersonic targets for long-range early warning and precision measurement radars, it is imperative to solve the challenges of robust multi-target initiation and rapid track convergence. Addressing the difficulties posed by this detection scenario, including significant range walk, strong Doppler coupling effects, slow track initiation convergence, and susceptibility to track association conflicts, a dual-pulse search-and-confirm waveform is designed in this paper. This design resolves the problems of single-frame radial velocity estimation for multiple targets and efficient dual-pulse integration without prior knowledge, achieving high-precision joint range-velocity estimation during the search-and-confirm phase. Furthermore, the detection process is optimized to enable rapid convergence of range errors during this phase, realizing robust and rapid initiation and tracking of dense hypersonic targets. Experimental results validate the effectiveness of the proposed method and detection process, demonstrating strong feasibility for engineering implementation. |
