Vedclass · Answer

(B) The maximum range of a radar is given by the radar range equation: $R_{max} = \left( \frac{P_t A^2 S}{4\pi \lambda^2 P_{min}} \right)^{1/4}$ Where: $P_t$ = Maximum transmitted power $A$ = Effective area of the receiving antenna $S$ = Radar cross-section of the target $\lambda$ = Wavelength of the radar signal $P_{min}$ = Minimum detectable power of the receiver From the equation,it is clear that $R_{max} \propto (P_t)^{1/4}$. Therefore,the maximum range is proportional to the fourth root of the maximum transmitted power.

The maximum range $(R_{max})$ of a radar is proportional to:
