Encapsulates a Sensor component for the flight control system.
Syntax:
<input> property </input>
<noise [variation="PERCENT|ABSOLUTE"] [distribution="UNIFORM|GAUSSIAN"]> number </noise>
<quantization
name=
"name">
</quantization>
</sensor>
Example:
<sensor
name=
"aero/sensor/qbar">
<input> aero/qbar </input>
<noise variation="PERCENT"> 2 </noise>
<quantization
name=
"aero/sensor/quantized/qbar">
</quantization>
</sensor>
The only required element in the sensor definition is the input element. In that case, no degradation would be modeled, and the output would simply be the input.
Noise can be Gaussian or uniform, and the noise can be applied as a factor (PERCENT) or additively (ABSOLUTE). The noise that can be applied at each frame of the simulation execution is calculated as a random factor times a noise value that is specified in the config file. When the noise distribution type is Gaussian, the random number can be between roughly -3 and +3 for a span of six sigma. When the distribution type is UNIFORM, the random value can be between -1.0 and +1.0. This random value is multiplied against the specified noise to arrive at a random noise value for the frame. If the noise type is PERCENT, then random noise value is added to one, and that sum is then multiplied against the input signal for the sensor. In this case, the specified noise value in the config file would be expected to actually be a percent value, such as 0.05 (for a 5% variance). If the noise type is ABSOLUTE, then the random noise value specified in the config file is understood to be an absolute value of noise to be added to the input signal instead of being added to 1.0 and having that sum be multiplied against the input signal as in the PERCENT type. For the ABSOLUTE noise case, the noise number specified in the config file could be any number.
If the type is ABSOLUTE, then the noise number times the random number is added to the input signal instead of being multiplied against it as with the PERCENT type of noise.
The delay element can specify a frame delay. The integer number provided is the number of frames to delay the output signal.
