Radar systems
Consider a radar with the following specifications: f = 1250MHz, maximum radar range of 220 nautical miles, for target with radar cross section σ = 1m ^ 2 with radar antenna dimensions 12 × 4m Antenna aperture efficiency ε_a = 0.55, minimum detectable signal of a pulse S_npn = 10 ^ (- 13) W and pulse width τ = 1.5μs. Calculate the following values: A) Effective A_em aperture level and G gain in terms of dB radar antenna. B) Transmitter...

The word radar is an abbreviation for Radio Detection and Ranging. Radar is used in many applications such as air traffic control, aircraft navigation, law enforcement and remote sensing. In this project you will investigate the different types of radars available and determine the best one to use in a speed gun application. Pulse Radar Draw a block diagram of a monostatic (same antenna is used to transmit and receive) pulse radar system and explain the role of each component....

A TV station has a weather radar which is monitoring an
approaching thunderstorm. The radar emits radio waves at a
frequency of 2900 MHz . The thunderstorm line is approaching the
radar installation at 45.0 km/h
Radio waves are reflected from the water drops in the
thunderstorms, and the reflected waves are detected back at the
installation. As measured by the receiver at the installation, is
the frequency of these reflected waves greater or less than 2900
MHz ?

Topic: The Radar Equation
A monostatic radar operates at 4 GHz and has a directive gain of 30
dB. The radar is used to track a target 10 km away and the radar
cross section of the target is 12 m^2. If the antenna of the radar
transmits 80 kW, calculate the power intercepted by the target.

Police use radar guns and the Doppler effect to catch speeders. A radar gun emits an electromagnetic wave that reflects from the oncoming car. The reflected wave returns to the police car with a frequency (measured by on-board equipment) that is different from the emitted frequency. If one such radar gun emits a wave whose frequency is 10.5 GHz. A frequency of 2.46 GHz is picked up by the radar gun when a hot shot in a sports car goes...
