The radar equation relates factors of the radar performance and practical effects to give an approximation for performance, where Pr is the expected receive power, Pt is the transmit power, Gt is the antenna gain, Gr is the receive gain, λ is the wavelength of ra...
Typically, radars illuminate their targets with an RF pulse and then listen for the return echo. Since the RF pulse propagates at the speed of light, the time it takes the echo to return is proportional to the distance from the target. The radar equation, as it is commonly known, defines...
Radar range equation Detection of objects using radar involves sophisticated signal processing. For a single pulse the following signal to noise ratio is: Observe that the received power drops with the fourth power of the range, so radar systems must cope with very large dynamic ranges in the re...
