System object: phased.AngleDopplerResponse
Package: phased
Calculate angleDoppler response
[RESP,ANG_GRID,DOP_GRID]
= step(H,X)
[RESP,ANG_GRID,DOP_GRID]
= step(H,X,ELANG)
RESP,ANG_GRID,DOP_GRID = step(H,X,PRF)
Note
Starting in R2016b, instead of using the step
method to perform the operation defined by the System object™, you can call the object with arguments, as if it were a function. For example, y = step(obj,x)
and y = obj(x)
perform equivalent operations.

. RESP
is
the complex angleDoppler response. ANG_GRID
and DOP_GRID
provide
the angle samples and Doppler samples, respectively, at which the
angleDoppler response is evaluated. This syntax is available when
the ElevationAngleSource
property is 'Property'
.
The size of the first dimension of the input matrix can vary to simulate a changing signal length. A size change can occur, for example, in the case of a pulse waveform with variable pulse repetition frequency.

Note
The object performs an initialization the first time the object is executed. This
initialization locks nontunable properties
and input specifications, such as dimensions, complexity, and data type of the input data.
If you change a nontunable property or an input specification, the System object issues an error. To change nontunable properties or inputs, you must first
call the release
method to unlock the object.

AngleDoppler response object. 

Input data as a matrix or column vector. If If 

Elevation angle in degrees. You can specify this argument as single or double precision. Default: Value of 

Pulse repetition frequency specified as a positive scalar. To enable this
argument, set the 

Complex angleDoppler response of 

Angle samples at which the angleDoppler response is evaluated. 

Doppler samples at which the angleDoppler response is evaluated. 
phased.AngleDopplerResponse
generates the response
using a conventional beamformer and an FFTbased Doppler filter. For
further details, see [1].
