Abstract:
1. A moving target radar tracking method, comprising: emitting a radar signal beam; sensing an echo of the radar signal beam from a moving target and producing a raw set of radar data about the moving target, including range, velocity, and acceleration; performing S/N (signal-to-noise ratio) enhancement of each raw set of radar data; performing trilateration on the S/N-enhanced sets of radar data in reference to a predefined 3-dimensional coordinate system having a first axis, a second axis, and a third axis to obtain three axis-oriented sets of radar data respectively in reference to the first axis, the second axis, and the third axis of the 3-dimensional coordinate system; performing S/N enhancement on the trilateration-resulted sets of radar data; and presenting the S/N-enhanced trilateration-resulted sets of radar data in a human-cognizable data form.
