| 英文摘要: |
| In the electronic warfare environment, the performance of radar and jammer will be affected by the lack of understanding of
the battlefield game environment and the inaccurate estimation of spectrum information. This paper studied the energy allocation problem
of radar transmission waveform and jamming waveform, and radar and jammer can obtain better performance by optimizing their own
transmission waveform in the process of confrontation. In reality, because the radar cannot obtain accurate target spectrum and jamming
spectrum, and the jammer cannot obtain accurate target spectrum and radar transmitted signal spectrum, the radar and jammer are taken
as leaders respectively, a hierarchical game model is established, and a double robust waveform design method is proposed. The
optimization model of dual robust transmit waveform is established under the energy constraint, and the dual robust radar transmit
waveform and dual robust jamming waveform are solved by Lagrange multiplier method. Simulation results show that the proposed method
can improve the radar parameter estimation performance and jammer performance in the worst case. |
