Technology / Radar / Ghost Effect: Sometimes when a radar signal hits a valid target, clutter may originate from multipath echoes created due to signal reflection from the ground, atmospheric particles or due to ionospheric reflection and/or refraction. The clutter is very bothersome because it appears to move and behave just like another normal target, thereby creating a ‘ghost’. Using a ground map of radar 's surrounding and eliminating all echoes that appear to originate from below the ground may help solve the ‘ghost’ problem.
