An object-detection radar for a drone sends out the signal shown in Figure P \(5=32\).
(a) Write an expression for the first two pulses of the signal.
(b) To avoid ambiguity, the radar receiver only accepts one pulse at a time. Considering the time for the pulse to reach an object and return to the receiver, what is the maximum distance that the radar can detect an obstacle? ( Hint: The speed of light is \(3 \times 10^{8} \mathrm{~m} / \mathrm{s}\).)
