coverageConfig
Syntax
Description
allows you to specify the position and orientation of the platform on which each sensor or
emitter is mounted.configs
= coverageConfig(sensors
,positions
,orientations
)
Examples
Obtain Coverage Configuration
Create a radar sensor and a radar emitter.
radar = radarDataGenerator(1,'Rotator');
emitter = radarEmitter(2);
Obtain coverage configurations based on the sensor's position information.
cfgs = coverageConfig({radar,emitter})
cfgs=2×1 struct array with fields:
Index
LookAngle
FieldOfView
ScanLimits
Range
Position
Orientation
cfgs2 = coverageConfig({radar, emitter},[1000 0 0 ; 0 1000 0])
cfgs2=2×1 struct array with fields:
Index
LookAngle
FieldOfView
ScanLimits
Range
Position
Orientation
Create a radar scenario and add the radar sensor and the radar emitter to the scenario.
sc = radarScenario; plat = platform(sc); plat.Sensors = {radar}; plat.Emitters = {emitter};
Obtain all coverage configurations in the scenario.
cfgScenario = coverageConfig(sc)
cfgScenario=2×1 struct array with fields:
Index
LookAngle
FieldOfView
ScanLimits
Range
Position
Orientation
Input Arguments
sc
— Radar scenario
radarScenario
object
Radar scenario, specified as a radarScenario
object.
sensors
— Sensors or emitters
sensor or emitter object | N-element cell array of sensor or emitter objects
Sensors or emitters, specified as a sensor or emitter object, or an
N-element cell array of sensor or emitter objects, where
N is the number of sensor or emitter objects. The applicable sensor
or emitter objects include radarDataGenerator
and radarEmitter
.
positions
— Position of sensor or emitter's platform
N-by-3 matrix of scalars
Position of sensor or emitter's platform, specified as an N-by-3 matrix of scalars in meters. The ith row of the matrix is the [x, y, z] Cartesian coordinates of the ith sensor or emitter's platform.
orientations
— Orientation of sensor or emitter's platform
N-by-1 vector of quaternions
Orientation of sensor or emitter's platform, specified as an N-by-1 vector of quaternions. The ith quaternion in the vector represents the rotation from the global or scenario frame to the ith sensor or emitter's platform frame.
Output Arguments
configs
— Sensor or emitter coverage configurations
N-element array of configuration structures
Sensor or emitter coverage configurations, returned as an
N-element array of configuration structures. N is
the number of sensor or emitter objects specified in the sensors
input or the number of sensors or emitters contained in the
radarScenario
object sc
. Each configuration
structure contains seven fields:
Fields of configurations
Field | Description |
---|---|
Index | A unique integer to distinguish sensors or emitters. |
LookAngle | The current boresight angles of the sensor or emitter, specified as:
|
FieldOfView | The field of view of the sensor or emitter, specified as a two-element
vector [azimuth ; elevation ] in
degrees. |
ScanLimits | The minimum and maximum angles the sensor or emitter can scan from
its
|
Range | The range of the beam and coverage area of the sensor or emitter in meters. |
Position | The origin position of the sensor or emitter, specified as a
three-element vector [X , Y ,
Z ] on the theater plot's axes. |
Orientation | The rotation transformation from the scenario or global frame to the sensor or emitter mounting frame, specified as a rotation matrix, a quaternion, or three Euler angles in ZYX sequence. |
You can use configs
to plot the sensor coverage in a
theaterPlot
using its
plotCoverage
object
function.
Note
The Index
field is returned as a positive integer if the input
is a sensor object, such as a radarDataGenerator
object. The Index
field is returned
as a negative integer if the input is an emitter object, such as a radarEmitter
object.
