Reducing Laser Profiles on a Tabletop Computer.

Standard numerical techniques for removing aircraft motion and discontinuities from airborne laser profiles are adapted to a desk-top computer. Because such a computer is much slower than a larger machine, analog active filters replace the numerical (Hamming) filters normally used. The computer prog...

Description
Summary:Standard numerical techniques for removing aircraft motion and discontinuities from airborne laser profiles are adapted to a desk-top computer. Because such a computer is much slower than a larger machine, analog active filters replace the numerical (Hamming) filters normally used. The computer programs are in BASIC, and listings are provided in an Appendix. Several examples of data editing procedures are given. (Author)
