Illustration of Radar Footprint Used in

Coverage Calculations






The radar coverage calculations incorporate the full  six DOF radar trajectory. 





The radar is located at the point Pm.

     αr  is the radar pointing angle.

     ζ is the radar squint angle.

     β is the horizontal radar half beamwidth                        
     γ is the vertical radar half beamwidth.


 The ellipse depicts one of the possible 3-dB
illuminated shapes and areas on the ground.

   For each radar position, the new footprint
shape and area is calculated .
