Transmitters and Receivers

Transmitters, receivers, coherent-on-transmit, and coherent-on-receive systems

Transmitters amplify signals before the radiator converts them into fields. A receiver preamplifier model applies gain to the incoming signal after collection and also adds receiver noise to the incoming signal. Examples illustrate coherent-on-transmit and coherent-on-receive radar systems.

Transmitters and Receivers

Transmitter
The transmitter models transmit power, transmit gain, and system loss.
Receiver Preamp
The preamplifier models receiver gain and noise.
