Answer / raj

It depends on pulse repetition frequency

Answer / navneet

depends on prf.... its right

Answer / sanjay

depends mainly upon radiated power.

Answer / black_mamba_007

range of radar increased depends on



Transmitted power increase

received power decrease

frequency (decrease)but limited by wavwlength

diameter of the aperture




Actually it is affected by almost all the factors present in the radar range equation.

Answer / mhk

It is the max. length that one can measure using a RADAR without any ambiguity at a fixed PRF.

It is mainly depends on the pulse repetition frequency (PRF)

but also depends on the following factors:

transmitted power
min. detectable strength of the received signal
tx. antenna gain
Rx. antenna gain
directivity of antenna

Band Name Frequency Range Wavelength Range Notes
HF 3–30 MHz 10–100 m coastal radar systems, over-the-
horizon radar (OTH) radars; 'high frequency'
P < 300 MHz 1 m+ 'P' for 'previous', applied
retrospectively to early radar systems
VHF 50–330 MHz 0.9–6 m very long range, ground
penetrating; 'very high frequency'
UHF 300–1000 MHz 0.3–1 m very long range (e.g. ballistic
missile early warning), ground penetrating, foliage
penetrating; 'ultra high frequency'
L 1–2 GHz 15–30 cm long range air traffic control and
surveillance; 'L' for 'long'
S 2–4 GHz 7.5–15 cm terminal air traffic control, long-
range weather, marine radar; 'S' for 'short'
C 4–8 GHz 3.75–7.5 cm Satellite transponders; a compromise
(hence 'C') between X and S bands; weather
X 8–12 GHz 2.5–3.75 cm missile guidance, marine radar,
weather, medium-resolution mapping and ground surveillance;
in the USA the narrow range 10.525 GHz ±25 MHz is used for
airport radar. Named X band because the frequency was a
secret during WW2.
Ku 12–18 GHz 1.67–2.5 cm high-resolution mapping, satellite
altimetry; frequency just under K band (hence 'u')
K 18–24 GHz 1.11–1.67 cm from German kurz, meaning 'short';
limited use due to absorption by water vapour, so Ku and Ka
were used instead for surveillance. K-band is used for
detecting clouds by meteorologists, and by police for
detecting speeding motorists. K-band radar guns operate at
24.150 ± 0.100 GHz.
Ka 24–40 GHz 0.75–1.11 cm mapping, short range, airport
surveillance; frequency just above K band (hence 'a') Photo
radar, used to trigger cameras which take pictures of
license plates of cars running red lights, operates at
34.300 ± 0.100 GHz.
mm 40–300 GHz 7.5 mm – 1 mm millimetre band, subdivided as
below. The frequency ranges depend on waveguide size.
Multiple letters are assigned to these bands by different
groups. These are from Baytron, a now defunct company that
made test equipment.
Q 40–60 GHz 7.5 mm – 5 mm Used for Military communication.
V 50–75 GHz 6.0–4 mm Very strongly absorbed by the
atmosphere.
E 60–90 GHz 6.0–3.33 mm
W 75–110 GHz 2.7 – 4.0 mm used as a visual sensor for
experimental autonomous vehicles, high-resolution
meteorological observation, and imaging.
UWB 1.6–10.5 GHz 18.75 cm – 2.8 cm used for through the
wall radar and imaging systems.
