A pulse having low peak power and long duration is require at transmitter for long range detection ,And at output of receiver the pulse should have short width and high peak power is required to achieve better range resolution .So to get the advantage of large range detection ability of long pulse and better range resolution of short pulse, pulse compression techniques are used
