satellite test range

The test principles and test methods of the antenna and satellite RF system in Compensated Compact Range are summarized, and the test errors are analyzed.

概要讲述了利用紧缩场进行卫星整星状态下的天线及卫星系统测试的原理及方法。文章还对该紧缩场的测试误差进行了全面的分析。

Compared to other types of compact range, the front fed Cassegrain compact range provides larger quiet zone and lower polarization, which satisfies the requirement to the polarization purity in the satellite test and polarization matrix measurement.

相对于其他类型紧缩场而言，前馈卡塞格伦紧缩场具有更大的口面利用系数和较低的交叉极化，可以满足卫星天线测量、交叉极化矩阵测量对极化纯度的要求。

US and South Korean officials say North Korea is planning to test fire a long range missile by pretending to launch a satellite into space.

美韩官员认为朝鲜假装发射卫星，事实上是测试发射远程导弹。

When the North test-fired a-range missile in 1998, it claimed it put a satellite orbit.

1998年北朝鲜 试射 了远程火箭, 朝鲜声称该火箭把一枚卫星送入轨道.
