It is well-known that astrophysical sources of electromagnetic radiation could be magnified by gravitational lenses. It is clear that gravitational radiation sources could be amplified by gravitational lenses also. Usually, gravitational waves differ from electromagnetic ones by two features: a) Gravitational waves are tensorial, but electromagnetic waves are vectorial; b).The typical gravitational wave length is much longer than typical electromagnetic wave lengh. We analyse which sources of gravitational radiation could be amplified significantly and which gravitational lenses could act effectively for gravitational radiation sources.
