Additionally, the sets demonstrated a serious problem with ground reflections.
2.
The net quality of a ground reflection depends on the topography of the surface.
3.
This provided the important advantage of allowing the radar to avoid ground reflections simply by pointing the antenna upward.
4.
Their equation did not assume Gaussian distribution nor did it include the effect of ground reflection of the pollutant plume.
5.
This way the ground reflection would simply be ignored, although at the cost of requiring the transponder to have two antennas.
6.
For mobility, better range, and for overcoming obstructions and ground reflection, a vehicle mounted version of BFSR has been developed.
7.
The resulting beam was so sharply focussed, spanning about 10 degrees, that it easily avoided ground reflections at even low altitudes.
8.
This would also have the side-effect of allowing the radar to avoid ground reflections simply by pointing the antenna away from the ground.
9.
The ground reflection of an airborne lidar gives a measure of surface reflectivity ( assuming the atmospheric transmittance is well known ) at the lidar wavelength.
10.
The new radars eliminated problems with ground reflections, allowing the missile to be fired at any visible target, no matter how close to the ground.
