Radar 4

Question 1

Explain the relationship between Pulse Width and Minimum Range.

Answer 1

Pulse Width determines the minimum range.
* The target must be greater than half the system Pulse Width from the antenna.

Question 2

Define Range Resolution.

Answer 2

Range resolution is the ability of a radar to resolve between two or more targets close together in range.

Question 3

Explain the relationship between PRF and Maximum Theoretical Range.

Answer 3

Maximum Theoretical Range is determined by the PRF.
* Maximum Theoretical range is determined by how long the receiver can ‘listen’ for the echo before the next pulse is transmitted.

Question 4

Describe Radar Horizon

Answer 4

Limitation of the radar range based on Line of Sight (LOS) and curvature of the Earth.
