Ground Order of-Battle Resolution -St-u-Vy
SUBJECT: Request for Evaluation
FOR: Chief, Research and Engineering Division, TSG/NPIC
3 MAY 1971
1. Reference is made to NPIC Memorandum NPIC/TSG/RED-45/71 dated
6 April 1971 (SpAD Project 011256).
2. SpAa-.Is evaluation of the technical performance aspects of the
subject study is given below.
Test Objectives
a. The introduction to the report does.not make-clear whether-
the phrasing of the. questions. to be answered.js.that of the briefing
authority, or whether it is the company's own -interpretation of a
general requirement. In any case,4more pertinent would have been
the following questions:
(1) What is the minimum ground resolution required for:
(a) Classification of targets?
(b) Identification of targets?
(c) Detailed analysis of equipment?
(2) What is the effect of stereo viewing on ground
resolution requirements?
4. Target Material
'a. By choosing as one of the target areas the Aberdeen Proving
Ground the company somewhat limited the scope of the study. This
facility had been visited previously by some of the PIs who took part
in the study while they were attending the Army PI school. Their
ground knowledge of the targets and their familiarity with other
imagery of the same targets undoubtedly led to false conclusions in
the report.
