Radar Range Calculator  

Where,
R_{Max} = Radar Range
P_{t} = Transmitted Pulse Peak Power
G = Maximum Power Gain of Antenna
S = Radar Cross Section Area
A_{e} = Antenna Aperture
P_{Min} = Minimum Detectable Signal of Receiver
Example:
Calculate the Radar Range for the given details.
Transmitted Pulse Peak Power (P_{t}): 25
Maximum Power Gain of Antenna (G): 20
Antenna Aperture (A_{e}): 15
Radar Cross Section Area (S): 10
Minimum Detectable Signal of Receiver (P_{MIN}): 5
Solution:
Apply Formula:
R_{Max} = ((P_{t} *G* S * A_{e}) / ( ( 4 * PI)^{2} * P_{Min}))
R_{Max} = ((25*20*15*10)/((4*3.14) 2 *5))
R_{Max} = ((75000)/ (12.56) 2*5))
R_{Max} = (75000 /157.75 *5)
R_{Max} = 75000 /788.768
R_{Max} = 95.0849933
Radar Range (R_{MAX}): 95.0849933
