Receiver

Receiver object belonging to satellite scenario

Description

The Receiver object defines a receiver object function belonging to the satellite scenario.

Creation

You can create Receiver object using the receiver object function of the Satellite, GroundStation, or Gimbal object.

Properties

Name — Receiver name

"Receiver idx" (default) | string scalar | string vector | character vector | cell array of character vectors

You can set this property only when calling Receiver. After you call Receiver, this property is read-only.

Receiver name, specified as a comma-separated pair consisting of 'Name' and a string scalar, string vector, character vector or a cell array of character vectors.

• If only one Receiver is added, specify Name as a string scalar or a character vector.

• If multiple Receivers are added, specify Name as a string vector or a cell array of character vectors. The number of elements in the string vector or cell array must be equal to the number of satellites being added.

In the default value, idx is the count of the Receiver added by the Receiver object function. If another Receiver of the same name exists, a suffix _idx₂ is added, where idx₂ is an integer that is incremented by 1 starting from 1 until the name duplication is resolved.

Data Types: char | string

ID — Receiver ID assigned by simulator

real positive scalar

This property is set internally by the simulator and is read-only.

Receiver ID assigned by the simulator, specified as a positive scalar.

MountingLocation — Mounting location with respect to parent

[0; 0; 0] (default) | three-element row vector of positive numbers

Mounting location with respect to the parent object, specified as a three-element row vector of positive numbers in meters. The position vector is specified in the body frame of the input parent.

MountingAngles — Mounting orientation with respect to parent object

[0; 0; 0] (default) | three-element row vector of positive numbers

Mounting orientation with respect to parent object, specified as a three-element row vector of positive numbers in degrees. The elements of the vector correspond to yaw, pitch, and roll in that order. Yaw, pitch, and roll are positive rotations about the parent's z - axis, intermediate y - axis and intermediate x - axis of the parent.

Example: [0; 30; 60]

Antenna — Antenna object associated with Receiver

gaussianAntenna object

Antenna object associated with the Receiver, specified as an antenna object. The default gaussian antenna has a dish diameter of 1 m and an aperture efficiency of 0.65.

SystemLoss — Total loss in Receiver

5 (default) | positive scalar

Total loss in the Receiver, specified as a real positive scalar. Units are in dB.

GainToNoiseTemperatureRatio — Gain to noise temperature ratio

3 (default) | scalar

Gain to noise temperature ratio of the antenna, specified as the comma-separated pair consisting of 'GainToNoiseTemperatureRatio' and a scalar. Units are in dB/K.

RequiredEbNo — Lowest Eb/No necessary for link closure

10 (default) | positive scalar

Lowest energy per bit to noise power spectral density ratio (Eb/No) necessary for link closure, specified as the comma-separated pair consisting of 'RequiredEbNo' and a positive scalar. Units are in dB.
