1. A method for processing a waveform comprising: receiving a first data set having a plurality of values based on a radar waveform return from a set of transmitted radar pulses in which the time separation between at least two neighboring pulses is at least equal to twice the shortest time separation between all of the other neighboring pulses in the set; and creating a second data set comprising the first data set minus at least one significant value from the first data set and its effects on other values within the first data set.
