Radar distance calculation

Radar distance calculation refers to the maximum distance that a radar can find a target under certain observation environments and certain probability of discovery and false alarm probability.
Radar distance calculation can calculate its performance based on radar parameters and is a very practical application.
The detection range of the radar is mainly related to the radar performance and the cross-sectional area of ??the target. Usually, the higher the radar transmission power, the higher the antenna gain and the receiver sensitivity, and the larger the cross-sectional area of ??the target, the farther the detection distance is.
In the application:
RMax = radar range
Pt = transmit pulse peak power
G = maximum power gain of the antenna
AE = antenna aperture
S = radar cross-sectional area
PMin = minimum detectable signal of the receiver
