2. Therefore, it is important t at the higher frequencies
the targets only be properly periodic and of known contrast : It in
not necessary that the edges be sharp or well-defined.
3. In a square array thwcald be three groupings oriented in
the same direction. The two moft probable frequency ranges will be:
1 - 10 5 50
10 - 100 50 - 500
100-1003 500-?
4. Information needed 25X1 A
a. Could they be int ted, and would they be
able to make such targets?
b. How much of an effort would be involved on their
part; and hoer much use Could they make of the techniques
_hey are developing under our other caitractt
e. How much time would be involved?
d. Estimate approximate fixed-price cost per target,
