Syntax

detections = detect(plat,time)
detections = detect(plat,signals,time)
detections = detect(plat,signals,emitterConfigs,time)
[detections,numDets] = detect(___)
[detections,numDets,sensorConfigs] = detect(___)

Description

detections = detect(plat,time) reports the detections from all sensors mounted on the platform, plat, at the specified time. Use this syntax when none of the sensors require information on signals present in the scenario.

detections = detect(plat,signals,time) also specifies any signals, signals, present in the scenario. Use this syntax when sensors require information on the signals.

detections = detect(plat,signals,emitterConfigs,time) also specifies emitter configurations, emitterConfigs. Use this syntax when sensors require information on the configurations of emitters generating signals in the scenario.

[detections,numDets] = detect(___) also returns the number of detections, numDets. This output argument can be used with any of the previous syntaxes.

[detections,numDets,sensorConfigs] = detect(___) also returns all sensor configurations, sensorConfigs. This output argument can be used with any of the previous syntaxes.

Input Arguments

collapse all

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

Simulation time, specified as a positive scalar.

Example: 1.5

Data Types: single | double

Signal emissions, specified as a cell array of signal emission objects such as radarEmission objects.

Emitter configurations, specified as an array of emitter configuration structures. Each structure has these fields.

FieldDescription
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 frame.

Output Arguments

collapse all

Sensor detections, returned as a cell array of objectDetection objects.

Number of detections reported, returned as a nonnegative integer.

Data Types: double

Sensor configurations, returned as an array of sensor configuration structures. Each structure has these fields.

FieldDescription
SensorIndex

Unique sensor index, returned as a positive integer.

IsValidTime

Valid detection time, returned as true or false. IsValidTime is false when detection updates are requested between update intervals specified by the update rate.

IsScanDone

IsScanDone is true when the sensor has completed a scan.

FieldOfView

Field of view of the sensor, returned as a 2-by-1 vector of positive real values, [azfov;elfov]. azfov and elfov represent the field of view in azimuth and elevation, respectively.

RangeLimits

Minimum and maximum range of sensor, in meters, specified as a 1-by-2 nonnegative real-valued vector of the form [rmin,rmax].

RangeRateLimits

Minimum and maximum range rate of sensor, in meters per second, specified as a 1-by-2 real-valued vector of the form [rrmin,rrmax].

MeasurementParameters

Sensor 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 sensor frame.
