实验室模拟测量是研究海杂波及海杂波背景下目标散射特性的一种有效手段,文中利用造波水池模拟生成海浪,并利用距离波门截取技术获取主波束照射区域内的海面回波,开展了海杂波的实验室模拟测量,该方法减少了造波池岸、天线旁瓣等的影响,测量的模拟海面散射系数及多普勒回波与海面实测结果较为一致。
Laboratory simulation measurement is an effective method to study the scattering characteristics of the target under sea clutter and sea clutter. In this paper, sea waves are simulated by using wave-making pool, and sea surface echoes in the main beam irradiation area are acquired by the distance-wave gate interception technique. The laboratory climatic measurement of sea clutter was carried out. The method reduced the effect of wave pool shore and antenna sidelobe, and the simulated sea surface scattering coefficient and Doppler echo were in good agreement with the sea surface measured results.
