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'

Input data as a matrix or column vector. If If 

Elevation angle in degrees. Default: Value of 

Complex angleDoppler response of 

Angle samples at which the angleDoppler response is evaluated. 

Doppler samples at which the angleDoppler response is evaluated. 
Calculate the angleDoppler response of the 190th cell of a collected data cube.
Load data and construct AngleDopplerResponse System object
load STAPExampleData; x = shiftdim(STAPEx_ReceivePulse(190,:,:)); hadresp = phased.AngleDopplerResponse(... 'SensorArray',STAPEx_HArray,... 'OperatingFrequency',STAPEx_OperatingFrequency,... 'PropagationSpeed',STAPEx_PropagationSpeed,... 'PRF',STAPEx_PRF);
Plot AngleDoppler response
[resp,ang_grid,dop_grid] = step(hadresp,x); contour(ang_grid,dop_grid,abs(resp)) xlabel('Angle'); ylabel('Doppler');
phased.AngleDopplerResponse
generates the response
using a conventional beamformer and an FFTbased Doppler filter. For
further details, see [1].
