A pulse radar system has a PRF-300Hz, an antenna with a 3-dB beamwidth of 1.5-degree, and an antenna scanning rate of 5 rpm. How many pulses will hit the target and return for integration?
• An X-band CW radar operates at a frequency of 10 GHz and triangularly sweeps a bandwidth of frequency
excursion of 2 MHz at a 200 Hz rate. The frequency difference between the transmit and receive signals
on the up-sweep is 65.51 kHz and on the down-sweep it is 82.65 kHz. Find the target range and radial
velocity.
An antenna is mounted on a 2 meter rod that is held out of level so that the antenna is offset by 0.4' from the bottom of the rod. What is the angular error of the rod? What is the vertical error of the measurement?

- Coexistence of radar systems. In this problem, we’re trying to determine whether two radars are interfering with each other. We will need to generate antenna patterns (uniform illumination, λ/2 spacing) for both radars and determine power densities and SNRs. Radar 1 Frequency = 3 GHz Peak power = 100 kW Circular array – diameter = 2 meters Transmit Loss = 2 dB Radar 2 Frequency = 3 GHz Peak power = 1000 W Circular array – diameter = 0.5 meters Duty 10% Dwell time = 1 ms Noise Figure = 4.5 dB Total System Losses = 10 dB Bandwidth = 1 MHz When Radar 2 is turned on.
