研究了一种设计最佳FSK/PSK雷达信号的方法。这种方法利用雷达目标的回波信息,通过不断循环迭代学习来设计最佳FSK/PSK雷达信号,使目标回波信噪比达到最大。仿真结果表明,这种方法可以在信噪比较低(0dB)的情况下,通过少数几次迭代即可收敛。 |

A Method for Designing Optimum FSK/PSK Radar Signals |
|
() |
Abstract: |
This paper discusses a method for designing optimum FSK/PSK radar signals by using the information carried by target echo,to make the maximum signal-to-noise ratio(SNR) of terget echo.Simulation results show that this algorithm converges well and has good noise margin at low SNR(0 dB). |
