The maximum range of a radar is
determined by which of the following
The pulse length of the radar
The range resolution of the radar
The pulse repetition frequency of the
The amplitude of the radar wave
What would be the maximum unambiguous
range of a radar with a pulse repetition
frequency (PRF) of 750?
Range folding occurs when back scattered
energy from a target reaches the radar
while another pulse is being
after another pulse has been
before another pulse is transmitted.
As range to a target increases, what
happens to (a) the radars pulse volume, and
(b) the power of the radar pulse?
1. (a) increases (b) increases
2. (a) increases (b) decreases
3. (a) decreases (b) decreases
4. (a) decreases (b) increases
Assuming two targets are equidistant from
a radar, how far must they be apart in order
for the radar to detect them separately?
Which element has the most significant
impact on the refraction of radar waves?
Under normal refractive conditions,
increase with height.
decrease with height.
remain equal with height.
