(a) Describe the algorithmic steps to compute the Short Time Fourier Transform (b) An alarm is recorded at 10 kHz sampling frequency. It is composed of two tones, one at 1.5kHz and one at 1.7kHz. The two tones alternate every 0.2 seconds. What window size would you use to resolve the two components in a Spectrogram? (c) Two airplanes are entering in a controlled airspace at two different speeds. Airplane A approaches at 70 m/s while airplane B approaches at 62 m/s. What is the minimum number of pulses that an air traffic control radar working at a carrier frequency of 1.2 GHz and a PRF of 1200 Hz should use to discriminate in Doppler the two airplanes? (d) A UAV is approaching a dam on which a metallic reflector is installed. Due to the water motion the dam vibrates at 4 Hz with a displacement of the reflector of 0.04 m in each direction. Sketch the micro-Doppler that the UAV will measure if it stops in front of the metallic reflector and observes it with a 24 GHz radar.
