FieldOfViewAndRangeRateModel

Field of view and range rate limits detectability model

Since R2025a

Description

A FieldOfViewAndRangeRateModel object contains a detectability model that assumes the sensor can detect targets whose positions are within its field of view and whose range rates are within the defined limits. The field of view is defined by azimuth, elevation, and range limits. You can use this model to define the detectability model for a CustomSensor object.

Creation

To create a FieldOfViewAndRangeRateModel object, use the sensorDetectabilityModel function with the "field-of-view" input argument. For example:

detectabilityModel = sensorDetectabilityModel("field-of-view-and-rangerate")

Properties

OriginPosition — Position of sensor with respect to target state reference frame

[0;0;0] (default) | 3-by-1 real column vector | 3-by-N real matrix

Position of the sensor with respect to the target state reference frame, specified as a 3-by-1 real column vector or a 3-by-N real matrix. Units are in meters.

• When specified as a 3-by-1 real column vector, OriginPosition takes the form [x;y;z].

• When specified as a 3-by-N real matrix, OriginPosition represents sequential frames. For example, if the sensor is mounted on a tower, and you know both the sensor's mounting position relative to the tower and the tower's position relative to the target frame, you can specify OriginPosition as [sensorMounting towerPosition], where sensorMounting is the sensor's mounting position relative to the tower and towerPosition is the tower's position relative to the target state's reference frame. The number of the frame, N, must be consistent across the OriginPosition and Orientation properties.

Example: [15 20 40]

OriginVelocity — Velocity of sensor with respect to target state reference frame

[0;0;0] (default) | 3-by-1 real column vector | 3-by-N real matrix

Velocity of the sensor with respect to the target state reference frame, specified as a 3-by-1 real column vector or a 3-by-N real matrix. Units are in meters per second.

• When specified as a 3-by-1 real column vector, OriginVelocity takes the form [vx;vy;vz].

• When specified as a 3-by-N real matrix, OriginVelocity represents sequential frames. For example, if the sensor is mounted on a plane, and you know both the sensor's mounting velocity relative to the plane and the plane's velocity relative to the target frame, you can specify OriginVelocity as [sensorMountingVelocity planeVelocity], where sensorMountingVelocity is the sensor's mounting velocity relative to the plane and towerPosition is the plane's position velocity to the target state's reference frame. The number of the frame, N, must be consistent across the OriginPosition, OriginVelocity, and Orientation properties.

Example: [1.5 1 4]

Orientation — Orientation of sensor with respect to target state reference frame

eye(3) (default) | 3-by-3 real matrix | 3-by-3-by-N real matrix

Orientation of the sensor with respect to the target state reference frame, specified as a 3-by-3 real matrix or a 3-by-3-by-N real matrix. Units are in degrees.

• When specified as a 3-by-3 real matrix, the Orientation represents the sensor's orientation relative to the target state reference frame.

• When specified as a 3-by-3-by-N real matrix, the Orientation represents sequential frames. For example, if the sensor is mounted on a tower, and you know both the sensor's mounting orientation relative to the tower and the tower's orientation relative to the target frame, you can specify Orientation as cat(3,sensorMountingOrientation,towerOrientation), where sensorMountingOrientation is the sensor's orientation relative to the tower and towerOrientation is the tower's orientation relative to the target state's reference frame. The number of the frame, N, must be consistent across the OriginPosition and Orientation properties.

AzimuthLimits — Azimuth limits of field of view

[-30 30] (default) | two-element real row vector

Azimuth limits of the field of view, specified as a two-element real row vector of the form [minAzi maxAzi]. Units are in degrees.

Example: [-45 45]

ElevationLimits — Elevation limits of field of view

[-15 15] (default) | two-element real row vector

Elevation limits of the field of view, specified as a two-element real row vector of the form [minEle maxEle]. Units are in degrees.

Example: [-20 20]

RangeLimits — Range limits of field of view

[0 100] (default) | two-element nonnegative row vector

Range limits of the field of view, specified as a two-element nonnegative row vector of the form [minRng maxRng]. maxRng must be greater than minRng. Units are in meters.

Example: [0 250]

RangeRateLimits — Range rate limits of target to be detectable

[-100 100] (default) | two-element real row vector

Range rate limits of the target to be detectable, specified as a two-element real row vector of the form [minRngRate maxRngRate]. maxRngRate must be greater than minRngRate. Units are in meters per second.

Example: [-80 80]

DetectionProbability — Probability of detecting target inside field of view and within range rate limits

0.9 (default) | scalar in the range (0,1)

Probability of detecting targets inside the field of view and within the range rate limits, specified as a scalar in the range (0,1).

Example: 0.88
