3. Notions on continuous radars
3.1 Basic principle
In cases where we are only interested in target speed :
speed control ;
doppler navigation ;
detection of the presence of fixed echoes in a medium.
The simplest solution is to emit a continuous wave of a specific frequency, and measure the difference between the frequency of the received wave and the frequency of the emitted wave.
The schematic diagram, shown in figure 34 , uses a coherent transmit-receive chain and two separate antennas.
These radars are simple in design,...
