2. If an aircraft is present in a certain area, a radar correctly registers its presence with probability .95. If it is not present, the radar falsely registers its presence with probability .03. We assume that aircraft is present with probability .2. (6) Use Notation: A fan aircraft is present), B (the radar registers an aircraft). a) Find the probability of false alarm. b) Find the probability of missed detection. c) Find the probability that an aircraft is not present...

Three radar stations, operating independently, are set to detect any aircraft flying through a certain area. Each station has a probability of 0.85 of detecting a plane in its area. If an aircraft enters the area, a. what is the probability that it is detected by all three radar stations? b. what is the probability that the plane is not detected by any of the radar stations? c. what is the probability that the plane is detected by only one...

Three radar sets, operating independently, are set to detect any aircraft flying through a certain area. Each set has a probability of 0.04 of failing to detect a plane in its area. Consider one of the radar sets. What is the probability that it will correctly detect exactly three aircraft before it fails to detect one, if aircraft arrivals are independent single events occurring at different times? (Round your answer to four decimal places.)

Problem 1. Plot the probability of false alarm given threshold voltage, Vt, from 0.1 to 100 mV given a noise voltage variance of 0.2 mV. Problem 3. Given the statistics in problem 1, find the threshold necessary to set the probability of false alarm equal to 10-4. Problem 4. Find the signal to noise ratio for a target that results in probability of detection equal to 0.9 (90%) given the system in problem 1 and the threshold found in problem...

3. You wish to design a Doppler radar system. A sinusoidal generator continuously generates the signal, S(t)-Acos2nt. This signal is transmitted to a speeding car, and the reflected signal is of the form rft)-Bcos[2lfe+Af)t]. The situation is shown below. The frequency difference (Doppler shift) is Af-10s, where s is the speed of the car in miles per hour. You wish to display the speed of the car on a voltmeter that reads from zero to 100 volts, and you wish...

Eighty percent of the light aircraft that disappear while in flight in a certain country are subsequently discovered. Of the aircraft that are discovered, 61 % have an emergency locator, whereas 89% of the aircraft not discovered do not have such a locator. Suppose a light aircraft has disappeared. (Round your answers to three decimal places.) (a) If it has an emergency locator, what is the probability that it will not be discovered? (b) If it does not have an...
