- Sainmhíniú a)a scale encircling the plan position indicator(PPI)scope of a radar on which the azimuth of a target from the radar may be measured.b)Reference limits inserted electronically at 10 degrees or 15 degrees intervals,extending radially from the relative position of the radar on an off-centre PPI scope.These are employed for target azimuth determination when the radar position is not at the centre of the PPI scope and hence the fixed azimuth scale on the edge of the scope cannot be used Tagairt Multilingual Aeronautical Dictionary(AGARD,1980)
