Synthetic range profile measurements of aircraft

This work reports practical results obtained from synthetic range profile (SRP) processing of commercial aircraft, using a pulse compression radar. The radar transmits pulses over a wide range of carrier frequencies, and by processing the returns, high resolution down-range profiles of airborne targets may be produced. Profiles obtained from large aircraft such as the Airbus are compared to those obtained from smaller, single engined aircraft. Helicopters have also been measured, and as expected, produced complex profiles due to the high Doppler frequency components of their rotor blades. The authors also discuss the data capture system.<
