Electronics and Radar Development Establishment (LRDE) is a laboratory of the Defence Research & Development Organisation (DRDO), India. Located in C.V. Raman Nagar , Bengaluru , Karnataka , its primary function is research and development of radars and related technologies. [ 1 ]
The radar mile is the time it takes for a radar pulse to travel one nautical mile, reflect off a target, and return to the radar antenna. Since a nautical mile is defined as 1,852 m, then dividing this distance by the speed of light (299,792,458 m/s), and then multiplying the result by 2 yields a result of 12.36 μs in duration.
By the 1970s, advances in electronics led to renewed interest in what was often called short-pulse radar. With further advances, it became practical to generate pulses having a width on the same order as the period of the RF carrier (T = 1/f).

Radars include airborne early warning (AEW), anti-submarine warfare (ASW), and even weather radar and ground tracking/proximity radar. The military uses radar in fast jets to help pilots fly at low levels. While the civil market has had weather radar for a while, [14] there are strict rules about using it to navigate the aircraft.

They are an aspect of electronic warfare involving actions taken under direct control of an operational commander to detect, intercept, identify, locate, record, and/or analyze sources of radiated electromagnetic energy for the purposes of immediate threat recognition (such as warning that fire control radar has locked on a combat vehicle, ship ...
The radar can also be vehicle or mast-mounted, to increase the detection capabilities. [15] For mobility, better range, and for overcoming obstructions and ground reflection, a vehicle mounted version of BFSR has been developed. The radar array is mounted on a 6 meter long telescopic mast on a jeep or truck platform. [10]
The radar measures the distance to the reflector by measuring the time of the round trip from emission of a pulse to reception, dividing this by two, and then multiplying by the speed of light. To be accepted, the received pulse has to lie within a period of time called the range gate .
