Signal Radiation, Collection, and Reflection

R2026b

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.

Objects

`phased.Collector`	Narrowband signal collector
`phased.Radiator`	Narrowband signal radiator
`phased.RISReflector`	Reconfigurable intelligent surface (RIS) reflector (Since R2025a)
`phased.WidebandCollector`	Wideband signal collector
`phased.WidebandRadiator`	Wideband signal radiator

Blocks

	Narrowband Receive Array	Receive narrowband radiation using phased array
	Narrowband Transmit Array	Narrowband transmit array
