Are There Any Restrictions On What Still-pipe Material Can Be Used?

Any type of conductive material can be used as long as it is compatible with the process media.If the material is not conductive it will be transparent to the radar-beams and therefore it will have no effect.

How to Calculate Target Height?

Target Height calculator uses Target Height = (Range Resolution*Range)/(2*Antenna Height) to calculate the Target Height, The Target height formula is defined as the distance of a target above the Earth's surface (height above ground). The height can be calculated from the target distance R and the elevation angle ε. Target Height is denoted by H_t symbol.
