RADAR RANGE EQUATION:

$R_{max} = (\frac{P_t G^2 (\lambda)^2 A}{(4\pi)^3 S_{min}})^{\frac{1}{4}}$

The factors influencing maximum range are as follows :

1. Transmitted power (Pt): if the radar range is to be doubled we have to increase a transmitted power by 16 times.

2. Frequency(f) : Increase in frequency increase the range

3. Target cross sectional area: Radar cross sectional area of the target is not a controllable factor.

4. Minimum received signal : A decrease in minimum receivable power will have the same effect has raising the transmuting power.
