5. A squadron of surveillance aircraft is tasked to close a 320 um wide channel with a. crossover barrier patrol to achieve at least 0.35 probability of detecting an intruder. Aircraft conduct search at speed 150 knots with sweep width 16 run, while the transiting speed of an intruder is 23 knots at best. Assume the inverse cube law for detection. (a) What is the maximal track space to achieve the detection probability 0.35? (b) How manyr aircraft are needed to form a symmetric crossover barrier? (c) Using the fewest aircraft required to form a symmetric crossover barrier to achieve detection probability at least 0.35, what is the actual detection probability
