In fact, the techniques of adaptive optics are already being used in radio astronomy. They are implicit in the basic imaging algorithms (e.g., CLEAN) used to produce maps from radio interferometers. In those cases, they are usually being used to correct for the artificial structure introduced by the way the interferometer samples the sky, rather than for structure imposed by the intervening material.
There was also a trial of adaptive antenna technology for radio astronomy in 2000. Interest in adaptive antenna design for terrestrial radio communications has also increased as portions of the radio spectrum can be more severely impacted by atmospheric phenomena than others and the amount of radio spectrum for terrestrial (and satellite) communications is decreasing as demand continues to increase.
Adaptive optics is a technology used to improve the performance of optical systems by reducing the effect of incoming wavefront distortions by deforming a mirror in order to compensate for the distortion. It is used in astronomical telescopes and laser communication systems to remove the effects of atmospheric distortion, in microscopy, optical fabrication and in retinal imaging systems to reduce optical aberrations. Adaptive optics works by measuring the distortions in a wavefront and compensat
With the latter technique, fainter natural reference stars can be used to measure the image motion, so the probability of finding such a reference star close to the astronomical object is higher, This concept of dual adaptive optics therefore provides a better sky coverage (up to 80% fora n 8-m telescope at 1- 2 µm).
Would adaptive optics be useful in radio astronomy? Can I get into Robotics after pursuing ECE (Electronics and Communication Engineering)? Does a laser's power diminish over distance?
In the future, adaptive optics will greatly enhance the resolution of the Hubble Space Telescope. False Optical telescopes are usually used at night, but radio telescopes can be used day and night.
A radio telescope is a specialized antenna and radio receiver used to detect radio waves from astronomical radio sources in the sky. Radio telescopes are the main observing instrument used in radio astronomy, which studies the radio frequency portion of the electromagnetic spectrum emitted by astronomical objects, just as optical telescopes are the main observing instrument used in traditional optical astronomy which studies the light wave portion of the spectrum coming from astronomical objects
This refers to adaptive optics which large optical telescopes and even radio telescope arrays use to carefully compensate for wavefront errors produced by various atmospheric effects (it's nonuniform water vapor and electron density in the ionosphere for radio; Would Adaptive Optics be Useful in Radio Astronomy?, and convection turbulence for optical; astronomical seeing).

How to image radio astronomy radio?
So, how do scientists make "radio pictures" of the objects in the Universe? Radio telescopes look like this. The dish of a radio telescope is made of metal and has a parabolic shape. The 140' telescope, pictured here, is pointing at an object in the universe. Radio waves emitted by that object hit the surface of the dish, and bounce.

What is radio astronomy?
Radio astronomy is a general term applied to the study of the radio emissions of stars and other objects in the heavens. Stars often give off visible light, which is electromagnetic energy. But they also emit a lot of electromagnetic energy below the optical band. These lower bands are given the general term radio bands, and a huge amount of work has been done (and continues) regarding imaging with radio waves. Radio astronomy actually outstrips optical astronomy in terms of how much it is used, though it almost certainly has a "lower profile" than observations made with the big optical telescopes. Different types of phenomenon or "reactions" occur in stars and other cosmological objects or structures, and these goings on result in the emission of energy (in different electromagnetic wavelengths). There are many that are only visible as radio sources, so we use radio astronomy to "see" them. We also use it to supplement imaging in optical wavelengths to give us better data as to what is out there. . Radio Astronomy is an academic, scientific, investigative discipline wherein stars, planets, and the interstellar and intergalactic media are studied at electromagnetic wavelengths of millimeters and centimeters, rather than nanometers as in optical, x-ray, UV, and gamma-ray detecting instruments.
