Range and velocity ambiguity resolution

Terminal Doppler Weather Radar enhancements

“…Velocity dealiasing is accomplished with this waveform by determining the true velocity that is consistent with the aliased velocity estimates from the different PRI pulse batches. The unfolded-velocity cluster method [11], applied to all PRI batches that are free of range overlays, is used to determine the true wind velocity.…”

Coherent Processing Across Multiple Staggered Pulse Repetition Interval (PRI) Dwells in Radar

“…Consider the 3 PRFs ( (2)(3)(4)(5)(6)(7)(8)(9)(10)(11) Hence, the performance would be ID times better compared to that of a single PRF system, which is PRF 2 . Typically the performance is enhanced by the maximum Doppler increment.…”

“…. , , , (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14) where g.c.d = greatest common divisor. Then the maximum resolvable range is the maximum range increment times that of a single PRF system of value PRF 2 .…”

“…Then the maximum resolvable range is the maximum range increment times that of a single PRF system of value PRF 2 . The product of (2-11) and (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14) results in a performance enhancement of…”

“…To overcome this problem due to the use of the CR theorem, a clustering algorithm has been proposed by Trunk and Rockett [5]. They used a variance for each PRF data to test if it is the real Doppler or range.…”
