Doubler/Amplifier Building Block for CW-Radar. Edition No. 1
VDM Publishing House, Sep 2010, Pages: 84
The CW-Radar measures the Doppler-frequency of the microwave radiation: A wave of fixed frequency (Continuous Wave, CW) is radiated through a high-gain antenna onto a moving target where it is reflected and the reflected wave is received by the radar antenna again. The reflected wave exhibits a frequency shift (Doppler-frequency) which is proportional to the radial velocity of the target and proportional to the frequency of the transmitted wave. This wave has frequency 24GHz, generated in the transmitter and after that there are some of parts. The thesis task is to build one part of a radar system which operates at 24 GHz, namely the building block that takes-in the 12 GHz oscillator signal to double the frequency to 24 GHz and amplify it as a driver signal for the transmit amplifier.
