You can simulate a phased array using the antenna, microphone, and sonar transducer System objects contained in this toolbox. You can choose from several common antenna and microphone element types but you can also define custom antenna or microphone elements. Antennas types include isotropic or cosine antennas for scalar fields and dipole antennas to simulate polarized electromagnetic fields. The toolbox also includes omnidirectional and custom microphones which are useful in audio applications. The toolbox supports sonar applications with isotropic projector and hydrophone System objects. Plotting tools let you display radiation patterns for power and directivity.
Phased array systems are also compatible with antennas from Antenna Toolbox™. Use of this toolbox requires an additional license. For an example of how to use Antenna Toolbox antennas in place of Phased Array System Toolbox™ antennas, see Using Antenna Toolbox with Phased Array Systems.
The toolbox also provides models for transmitting and receiving amplifiers.

Cosine antennas have response patterns consisting of cosine functions raised to user-specifiable power.
You can specify the response pattern of a custom antenna element as a function of azimuth and elevation.
Isotropic antennas have response patterns that are uniform in all directions.
Short-dipole antenna elements radiate linearly-polarized electromagnetic fields.
Crossed-dipole antenna elements radiate circularly-polarized electromagnetic fields.
You can use Antenna Toolbox antennas in your Phased Array System Toolbox simulation.
Radiation patterns describe fields radiated by antennas and transducers and can be used to analyze directivity and gain.
Polarized electromagnetic fields.
This section introduces the concept of baseband signals and defines the local and global coordinate systems used in the toolbox.
Phased Array System Toolbox uses the International System of Units (SI).
