Limitations of RADAR are:
RANGE DISCRIMINATION:
It is the ability of the RADAR set to clearly distinguish two small targets on the same bearing at slightly different ranges. The distance between the two targets is equal to or less than ½ PL .
BEARING DISCRIMINATION:
It is the ability of the radar set to clearly extinguish two targets of the same range and slightly different bearings.Factor affecting bearing discrimination : HBW
MINIMUM RANGE:
THE PULSE LENGTH : The TR circuit prevents the TX of any signal before receiving it. Hence, the theoretical minimum range of detection is repeated by half PL in minutes.
A PL of 0.2 micro would have a range of 30 mtrs.
