The CZT is more flexible than FFT in calculating the frequency spectrum; therefore it is used in various fields such as radar ranging and power prediction.
The development of new tools will be crucial for the interpretation of much larger data sets from WISE, Gaia, JWST, or NEOShield-2, but also for the operations and scientific exploitation of the Hayabusa-2 mission.Our approach is to combine different methods and techniques to get full information on selected bodies: lightcurve inversion, stellar occultations, thermo-physical modeling, radiometric methods, radar ranging and adaptive optics imaging.
Fortunately, radar ranging has refined the asteroid's orbit precisely enough to show that there's no chance of it hitting Earth in the next 100 years.
The A-1C (M) lead-computing sight was the first fighter aircraft gunsight to employ radar ranging. The sight had its roots in experimental sight development that began in 1942, during World War II.
The A-1C(M) lead-computing sight was the first fighter gunsight to employ radar ranging. It was widely used in Korea where it received a mixed reception by the F-86 pilots who depended upon it.
As in radar ranging, the pilot pressed the electrical caging button and maneuvered the aircraft so that the reticle dot--called the pipper--was on target.
After the tests were completed, Gabreski's team of veteran pilots still wanted to "do away with the radar ranging and the intricate, highly complicated electronic equipment." (54) The commander of the Air Proving Ground Command, Maj.
The Air Proving Ground Command's conclusion was in keeping with the views espoused by the Fifth Air Force, whose commanders believed that the fourteen aces queried by General Vandenberg were probably not well-trained in the use of the radar ranging gunsight and had served in Korea when the gunsight reliability problem was at its worst.
Nevertheless, radar ranging by Steven Ostro (Jet Propulsion Laboratory) and others has pinned down Toutatis's orbit so precisely that we know for certain that it will not hit Earth during at least the next 65 years, and that the chance of a collision is extremely minuscule for at least several centuries after that.
The radar ranging will also yield an even better orbit, probably adding more centuries of not having to worry about a collision.
