| dc.description.abstract | The radar transmitter subsystem generates the radio frequency (RF) energy required for the illumination of a remotely situated target of interest. Targets may include aircraft, ships, missiles and even weather phenomena such as rain, snow and clouds.
The radar transmitter produces the short duration high – power RF pulses of energy that are radiated into space by the antenna. The transmitter must have the ability to generate the required mean RF power and the required peak power: The transmitter must have a suitable RF bandwidth, the transmitter must have a high RF stability to meet signal processing requirements, the transmitter must be easily modulated to meet waveform design requirements, the transmitter must be efficient, reliable and easy to maintain and the life expectancy and cost of the output device must be acceptable.
The radar transmitter is composed of many different components. And the purpose of this thesis just gives step-by-step designs of three components of radar transmitter: band pass filter, power amplifier, and antenna. The simulation design uses Advanced Design System software (ADS) 2009 version (donated by Agilent’s Technology for 6 months using freely). And the circuit boards will be tested in the International University’s Laboratory. | en_US |
