Platform.emit

Radiate signals from emitters mounted on platform

Syntax

[signals,emitterconfigs] = emit(ptfm,time)

Description

[signals,emitterconfigs] = emit(ptfm,time) returns signals, signals, radiated by all the emitters mounted on the platform, ptfm, at the specified time. The function also returns all emitter configurations, emitterconfigs.

Input Arguments

ptfm — Scenario platform

Platform object

Scenario platform, specified as a Platform object. To create platforms, use the platform method.

time — Emission time

0 (default) | positive scalar

Emission time, specified as a positive scalar.

Example: 100.5

Data Types: single | double

Output Arguments

signals — Signals radiated by emitters on platform

cell array of emission objects

Signals radiated by emitters on platform, returned as a cell array of radarEmission and sonarEmission objects.

emitterconfigs — Emitter configurations

structure

Emitter configurations, returned as a structure. An emitter configuration has these fields:

Field	Description
EmitterIndex	Unique emitter index, returned as a positive integer.
IsValidTime	Valid emission time, returned as 0 or 1. IsValidTime is 0 when emitter updates are requested at times that are between update intervals specified by the UpdateInterval property.
IsScanDone	Whether the emitter has completed a scan, returned as true or false.
FieldOfView	Field of view of the emitter, returned as a two-element vector [azimuth; elevation] in degrees.
MeasurementParameters	Emitter measurement parameters, returned as an array of structures containing the coordinate frame transforms needed to transform positions and velocities in the top-level frame to the current emitter looking-angle frame.

Data Types: single | double
