“…Thus the area equivalent of targets entering the element will be 2h/(nV) = a (let). Similarly, the contribution from the neighbouring zones (2) or (4) will be 2M!lv/(rcV) = /3 (let). Thus for the second area element b (i.e., r+l=2), 71 = a + 2/3.…”

“…The rth term denominator in the expression for failure is [A+-1).2wI -YJ-In Table 2, the gammas being the sum of all targets (area equivalents) present in all elements upto the 7th element are given. By inference, for the (r+ 1)th element we have yi = [3.14r-6.7 + 6.7 X (0.68)' ]a + q3 (2) The Eqn. (2) can be used for r < r0 where r0 is determined from the equation…”

When a target has an apriori existence in an area A and a fraction Q of the area is searched, there are well-known expressions for the detection probability when the target is stationary. In this paper the detection probability is worked out for a more important case when the target is in motion. It must be assumed, however, that the target manages to remain in the area in which it has apriori existence by permitting suitable changes in its direction of motion. The detection probability will depend on the ratio of the speeds of the target and the searcher in a complex way. The computation should involve a computer programme but analytical expressions can be approximately derived for I#
