% 3D radar model for use with Kalman Filters.
Since version 2014.1
--------------------------------------------------------------------------
Form:
[y, sN, v] = MeasRadar( x, d )
--------------------------------------------------------------------------
------
Inputs
------
x (:,1) Target ECI state [r;v] (km,km/s)
d (1,1) Radar data structure
.lambda (1,1) Wavelength (m)
.noise (4,1) 1 sigma noise [range;rangeRate;
azimuth;elevation]
.qECIToBody (4,1) Quaternion from ECI to body
.qBodyToRadar (4,1) Quaternion from body to radar
.xRadar (6,1) Radar ECI state [r;v] (km,km/s)
.horizonAngle (1,1) Horizon angle for acquisition
.sigma (1,:) Radar crosssection
-------
Outputs
-------
y (4,1) Measurements [range;rangeRate;azimuth;elevation]
sN (1,1) Signal to noise ratio (dB)
v (1,1) 1 if sensor is visible.
