[T.sup.R.sub.PK] is the modulation transfer function for SAR, which includes the tilt modulation, hydrodynamic modulation, polarization angle modulation, range and azimuthal direction modulation, and velocity bunching modulation.
For example, in great value priority, our interspace is [Z.sup.n]; in the case of a transfer function (TF), we have [[0,1].sup.n] and {Space functions} in angle modulation. The second step transforms from the interspace ([Z.sup.n], [[0,1].sup.n], {Space functions}) into abinary space.
The angle modulation technique was applied to network reconfiguration problems in  using a binary PSO method.
For the case of angle modulation, there is space to perform binarizations on new metaheuristics, where different variations of angle modulation can be explored.
In this context, feature selection (FS) has been resolved using angle modulation and the set-based approach.

It covers signal and linear systems analysis, linear modulation techniques, angle modulation and multiplexing, principles of baseband digital data transmission, an overview of probability and random variables, random signals and noise, noise in modulation systems, principles of digital data transmission, advanced data communications topics, optimum receivers and signal-space concepts, and information theory and coding.
Mathematically, both these forms of angle modulation can be represented by
For narrowband angle modulation, the level of each sideband is
In PSK, angle modulation is applied to a sinusoidal carrier to create switching phase states at a rate equal to the applied digital data stream.
