A radar has a linear FM modulated pulse from 34GHZ to 35GHz. a. What is the range resolution? The radar has a 1ms transmit pulse width and uses stretch processing in the receive mixer. The receiver local oscillator ramp starts at a frequency of 33GHz at same time the transmit pulse is sent. b. What is the IF frequency of a target at 4 km?

A radar transmits a pulse every 0.5 ms. It transmits an up-chirp of the duration of 0.01 ms with a bandwidth of 50MHz and starting at 0 Hz. Sketch the time frequency distribution the transmitted train of pulses (consider just 4 pulses in the sketch).
A Radar transmits a 6µSec pulse observed two targets at the same azimuth and elevation. One target is 610 m behind the other. Since this distance is less than the range resolution, only one pulse will be received. How long will this pulse live? (c=3x108)
