Signal Radiation and Collection

Narrowband and wideband signal radiation and collection by phased arrays

Radiators create the electromagnetic or acoustic fields that propagate through space, air, or water. Collectors transform those fields back into electronic signals at the receiver. Phased Array System Toolbox™ System objects and Simulink® blocks simulate radiation and collection processes for narrowband and wideband signals.

Radiation and Collection

Signal Radiation

Simulate the radiated fields from antennas and arrays.

Signal Collection

Simulate the incoming fields at antennas and arrays.


Standards and Conventions

This section introduces the concept of baseband signals and defines the local and global coordinate systems used in the toolbox.

Units of Measure and Physical Constants

Phased Array System Toolbox uses the International System of Units (SI).
