Here's a suggestion.
TX Pulse ONE: Take the first sample say 5uS after the TX pulse, then take one at 15uS, and store them.
TX Pulse TWO: Take the first sample at 5uS and the SECOND sample at 20uS, and store them.
TX Pulse THREE: Take the first sample at 5uS and the SECOND sample at 25uS, and store them.
Repeat this process all the way until you have 60uS between P1 and P2, in 5uS increments.
When you are done with the above, you will have a "profile" of the target and it's surroundings. Integrate the results for EACH curve to provide a "signature" for the target object, then store these in a look-up table.
You could take upto TEN reading per curve for even better accuracy, as you would be defining the dv/dt of each target.
