摘要/Abstract

摘要： 针对射频仿真中宽带相控阵雷达海面场景散射回波快速、精确模拟的难点问题,有效结合时域近似方法和频域分析变换方法,提出基于时域近似—频域变换混合的海面场景散射回波快速计算方法,利用频域分析方法对海上目标/干扰进行精细化散射回波模拟,采用时域近似方法对大面积海杂波背景进行快速回波计算,通过矢量合成,模拟生成宽带相控阵雷达海面目标/干扰场景回波信号。仿真测试结果验证了该方法的有效性,表明该方法既可保证目标及干扰模拟的精确性,又可保证大场景回波模拟的快速性。

Abstract: Aiming at the problem of fast and accurate simulation of sea -scene scattering echo for wide-band phased array radar in radio frequency simulation, an efficient calculation method is proposed based on the time-domain approximation and frequency-domain transform. The frequency-domain transform method is used to calculate the scattering echo signal accurately, and the time-domain approximation method is used to calculate the echo signal of the large area of sea-clutter background. Then the scattering echo signal for wide-band phased array radar of the sea-scene is generated through vector summation. The simulation results validate this hybrid method. It shows that this hybrid method not only ensures the accuracy of the target/interference scattering echo signal simulation, but also ensures the rapidity of the large area of sea-clutter echo signal simulation.

Key words: wide-band phased array radar, scattering echo signal, radio frequency simulation, sea-scene
