Final answer:

To calculate the maximum detection range of a radar system with specified parameters, one would use the radar range equation, which takes into account the power output, antenna gain, signal wavelength, target radar cross-section, receiver noise figure and other constants. however the specific value cannot be provided without additional necessary constants and details.

Step-by-step explanation:

To determine the maximum detection range of a radar system operating at 6 GHz with a 3 MW power output, an antenna diameter of 5m a receiver bandwidth of 1.5 MHz, and a 12 dB noise figure for a 1 m2 target, we use the radar range equation:

R = \((\frac{P_{t}G^{2}\lambda^{2}\sigma}{(4\pi)^{3}kT_{0}LF_{n}})^{\frac{1}{4}}\)

Where:

  • Pt = transmitter power
  • G = antenna gain
  • \(\lambda\) = wavelength of the radar signal
  • \(\sigma\) = radar cross-section of the target
  • k = Boltzmann's constant
  • T0 = standard temperature in Kelvin
  • L = system losses
  • Fn = noise figure of the receiver

Given the specific details and the formulas for antenna gain and wavelength, we could calculate the maximum detection range for specified conditions. Please note that the actual calculation is not provided as it requires additional constants and loss factors that are not mentioned in the question.
