Subrefraction. A reversal of the effect is also possible. Sub-reaches by diversion of the beam in direction of above affect not noticeable disturbing, however, so like an overreach. Radar …

Sub-refraction causes the radar to overshoot targets that would ordinarily be observed under standard atmospheric conditions (Figure 1) and results in a reduction in the operational range …

In this module, we'll look at conditions that can reduce propagation ranges: skip zones, holes, interference patterns and subrefraction. Surface-based ducts can create regions of extended …

正折射包括正常折射 ( 也称标准折. ( trapped refraction) 等. 表 1 给出了各种折射类型的存在条件 . 数 . 表面波导一般出现在大气较稳定的晴好天气里 , 此时低层大气往往有一个比较稳定的. 逆 …

N increases with height, subrefraction occurs and the rays will bend upward. If N decreases at a rate between 418 79 and 157 km -1, superrefraction occurs and the rays will bend downward …

Abstract: Subrefraction is a kind of refractive type, although it appears less probability, however, it has a significant effect on the electromagnetic wave propagation. Subrefraction has …

Subrefraction is a abnormal refractive structure which appears in atmospheric environment, whose influence on electromagnetic waves propagation is opposite to that of evaporation duct. …

Subrefraction causes the radar to overshoot targets that are normally detected (fig. 2-15, view B). Subrefractive conditions are generally rare, and usually occur in desert regions and on the lee …

2014年7月11日 · Even if an evaporation duct is generally present in the maritime environments, situations with no ducts may also occur. Such situations are referred as subrefraction cases …

Subrefraction is a abnormal refractive structure which appears in atmospheric environment, whose influence on electromagnetic waves propagation is opposite to that of evaporation duct.
