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.

Topics

Transmitters and Receivers

Transmitter
The transmitter models transmit power, transmit gain, and system loss.
Receiver Preamp
The preamplifier models receiver gain and noise.
Modeling Transmitter and Receiver with Increasing Levels of Fidelity
Use phased.Transmitter and phased.Receiver system objects to model hardware effects prior to radiation from an antenna array. (Since R2025a)
