AngleDoppler response
The AngleDopplerResponse
object calculates
the angleDoppler response of input data.
To compute the angleDoppler response:
Define and set up your angleDoppler response calculator. See Construction.
Call step
to compute the angleDoppler
response of the input signal according to the properties of phased.AngleDopplerResponse
.
The behavior of step
is specific to each object in
the toolbox.
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.
H = phased.AngleDopplerResponse
creates
an angleDoppler response System object, H
.
This object calculates the angleDoppler response of the input data.

Signal propagation speed Specify the propagation speed of the signal, in meters per second, as a positive scalar. You can specify this property as single or double precision. Default: Speed of light  

System operating frequency Specify the operating frequency of the system in hertz as a positive scalar. The default value corresponds to 300 MHz. You can specify this property as single or double precision. Default:  

Source of PRF values Source of the PRF values for the STAP processor, specified as
Default:  

Pulse repetition frequency Specify the pulse repetition frequency (PRF) in hertz of the input signal as a positive
scalar. This property applies when you set the Default:  

Source of elevation angle Specify whether the elevation angle comes from the
Default:  

Elevation angle Specify the elevation angle in degrees used to calculate the angleDoppler response as a
scalar. The angle must be between –90 and 90. This property applies when you set the
Default:  

Number of samples in angular domain Specify the number of samples in the angular domain used to calculate the angleDoppler response as a positive integer. This value must be greater than 2. You can specify this property as single or double precision. Default:  

Number of samples in Doppler domain Specify the number of samples in the Doppler domain used to calculate the angleDoppler response as a positive integer. This value must be greater than 2. You can specify this property as single or double precision. Default:
