法国汤姆逊无线电公司发展了一种名为“罗密欧”(Rom eo)的毫米波雷达,供直升飞机驾驶员在夜间或气象条件不好的情况下便于选择没有障碍物的航路。对于给定的天线尺寸,波长越短,角分辨力越好。为此,汤姆逊无线电公司为“罗密欧”雷达设计了约为94千兆赫的固态辐射源,并采用连续波、线性频率调制技术。这些技术使该雷达具有探测小目标所需的功率和分辨力。“罗密欧”雷达在探测距离为几公里时,搜索范围:方位120°,
France’s Thomson radio company has developed a millimeter-wave radar called the Rom eo that makes it easy for helicopter pilots to choose an unobstructed fairway at night or in bad weather. For a given antenna size, the shorter the wavelength, the better the angular resolution. To this end, Thomson Radio designed a solid-state radiation source of approximately 94 Gigahertz for the “Romeo” radar, using continuous-wave, linear frequency modulation techniques. These technologies make the radar the power and resolution necessary to detect small targets. “Romeo” radar in the detection range of a few kilometers, the search range: 120 ° orientation,
