| 摘 要： | 介绍了调频连续波高度表和脉冲雷达高度表的测高原理,分析了两种体制高度表在复杂地形下使用时产生误差的原因,并且给出了两种高度表在复杂地形剖面场合下的机载试验结果。指出调频连续波高度表通常使用在地形剖面较平坦的场合(如水面),在复杂地形剖面场合下(如地形匹配、地形跟踪等)通常应使用脉冲雷达高度表。

| Abstract: | Introduces the height finding theory of the continuous wave frequency modulation(CWFM) altimeter and the pulse radar altimeter,analyzes the reason why the two kinds of altimeters were used in complex terrain to cause errors,and also gives out the experiment result that the plane mounted with the two kinds of altimeters flew in complex terrain section occasion.Pointes out that the CWFM altimeter was usually used in flat terrain section occasion(such as water face),and the pulse radar altimeter was normally used in complex terrain section occasion(such as terrain matching and terrain tracking etc). |
