2. (20 points) The Watchman family of S-Band medium-range radars is designed to provide terminal area/approach surveillance and ground controlled approach surveillance developed by Plessey Radar Ltd during the 1970s. The radar operates in 2,750 - 3,050 MHz, and can generate LFM waveform with a long pulse duration (20 microseconds) and achieve 60m range resolution. a) (10 points) According to the range resolution, find out the waveform bandwidth. b) (10 points) Calculate the waveform's chirp rate, and compression ratio. 2.
