What is radar ranging?

Radar Ranging is an Activity of a RADAR system to measure range of a particular object from the RADAR's own location the object can be aircrafts, ships or other objects like buildings.

Usually Ranging is done by means of transmitting a pulse and receive echoes from it where the range is measured from time differences(or Delay) between departure and arrival of pulse , this ranging method is called as "Pulse Delay Ranging"

Other ranging method is Doppler based ranging where range is measured by means of Doppler effect

EDIT- it seems i need to re-construct the answer
