Simulation and Design of 24GHz Radar transmitter system
Abstract: In the new century, with the popularity of radar applications, a variety of radar systems are applied to various equipment and machines. Among them, the 24GHz radar system, because of its low cost and price, Small volume requirement has been widely used in radar market. As an important part of radar system, 24GHz radar transmitter is also the most expensive part of radar system, and it has received great attention in the radar market. There are bright prospects for the future. On the basis of some previous scholars' research, I have studied the construction of 24GHZ radar transmitter system, combined with ADS simulation and PCB board diagram.The performance parameters of the designed radar transmitter system are obtained by ADS radio frequency simulation software, and the performance parameters of the radar transmitter system are analyzed. Judging whether it meets the performance requirements of radar transmitter, selecting mixer and amplifier chip according to these parameters, drawing the PCB board diagram by AD software, drawing the PCB board diagram of the core device, and using these parameters to select the mixer and amplifier chip which meet the design requirements, and draw the PCB board diagram of the core device. A radar transmitter system is designed to meet the requirements of practical production.
