Arduino radar search system [2]

October 11, 2015

I transferred the power received by the rotating patch array to voltage and recorded it with the Arduino computer. Moreover, the power received by the patch array consists of an RF signal. A rectifier is therefore placed at the end of the patch array so as to convert the RF signal to a DC signal. Between the antenna and rectifier is a matching circuit, which serves to transfer the largest possible power. Nevertheless, the received voltage is too small to be recognized by the Arduino computer. As a result, I have used two coil inductors to make the voltage larger. Another issue that needs to be addressed is how to transfer direction and distance data to the flying control system Pixhawk. I discovered there is an agreement—MAVLink—whose operation level is higher than the remote control. By using this agreement, I can cover the GPS signal with the Arduino searching system commands.
