A) proportional to the cube root of the peak transmitted power
B) proportional to the fourth root of the peak transmitted power
C) proportional to the square root of the peak transmitted power
D) Not related to the peak transmitted power at all
Correct Answer: B
Solution :
Maximum Range of the radar is given by \[{{R}_{\max }}={{\left( \frac{{{P}_{t}}{{A}^{2}}\,S}{4\pi {{\lambda }^{2}}\,{{P}_{\min }}} \right)}^{1/4}}\] Where Pt : peak value of transmitted power A: caputre area of the receiving antenna S: radar cross-sectional area \[\lambda \] : wavelength of RADAR wave \[{{\operatorname{P}}_{min}}\]: receivable power of the receiver
