Radar Observer · Performance — Minimum Range
A radar's minimum detection range is governed mainly by:
- ABeam width and antenna rotation rate
- BPulse length and recovery time of the receiver✓ Correct
- CThe range scale selected
- DThe number of range rings
Explanation
While the transmitter is firing a pulse the receiver is blanked, so very close echoes are not seen until the pulse ends and the receiver recovers. A shorter pulse gives a smaller minimum range.
