Elevation measuring device and elevation measuring program

摘要

PROBLEM TO BE SOLVED: To provide a target based on the arrival elevation angle of the direct signal even when a direct signal input from the target without passing through the ground or the sea surface and a reflected signal input from the target via the ground or the sea surface interfere with each other. Measure the height with high accuracy. Reflection from a target T to a radar antenna A via the ground or the sea surface based on the distance between the radar antenna A and the target T and the arrival elevation angle of a direct signal from the target T to the radar antenna A. The height of the target T is calculated multiple times at a plurality of distances between the radar antenna A and the target T by the target height calculation unit 21 that separates the arrival elevation angle of the signal and calculates the height of the target T. With respect to the calculation result of, the object height averaging unit 22 which excludes the calculation result of the height of the target T having the upper value and the lower value and calculates the average of the calculation result of the height of the target T which is not excluded. The object height measuring device 2 is provided with the above. [Selection diagram] Fig. 1
