| Summary |
"Design efforts concerning the problem of detecting moving ground targets from an airborne platform with a noncoherent radar have been concentrated in the area of video filter design. The filter formulation generally follows an empirical path with no generally acceptable criterion for an optimum processor. This Thesis considers several problem formulations which are based on a Neyman-Pearson detection criteria. A square-law second detector is assumed and the resulting likelihood ratio shown to be too complex for closed form solution. The problem is reformulated in terms of sequences using complex random variable representations and the likelihood ratio is investigated. A test statistic is derived and discussed in terms of a practical implementation. A suboptimum receiver is implemented in the video frequency region and compared with existing MTI processors by using computer simulation programs. A clutter rejection video filter shaped in accordance with the optimum receiver derivation is shown to have some advantage over conventional shaping with which it is compared"--Abstract, leaf ii. |
