Radar Range Equation
In radar system, range of the target is easily determined using received power of the echo signal.
In simple equation Pr = Pt / (4*PI*r2)
Here Pr is the received power, Pt is the peak transmit power, here r is the distance of target from radar (i.e. radar range). This equation is for isotropic antenna. Following equation or formula is used for directional antenna is mentioned below. This equation is used here for radar range calculator.
Method:2 of Maximum Radar range calculation
Another equation to determine maximum radar range is mentioned below.
Assumption: T of 300 Kelvin and K = 1.38e-23
INPUTS: Freq(GHz) = 5, Antenna Diameter = 5 meter , Radar cross section =1 m2, Peak pulse power = 2.5e6, Receiver BW (MHz) = 1.6, NF = 12dB
OUTPUT = 550 Km
Maximum radar range can alsobe calculated as per following radar equation or formula.
