Acoustooptical processor for radio signals with discrete frequency modulation
Autor: A. P. Lavrov, Sergey V. Dmitriev, N. A. Esepkina
Publikováno v: Technical Physics Letters. 23:54-56
A study is made of a processor for pulsed radio signals with discrete frequency modulation, where the frequency varies discontinuously within a pulse and takes on N different values. The spectral components are separated with an acoustooptic spectrum

Use of a scanning charge-coupled photodetector for compression of optical signals with linear wavelength modulation
Autor: N. A. Esepkina, A. P. Lavrov
Publikováno v: Technical Physics Letters. 23:43-45
An analysis is made of a processor for compression of optical signals with linear wavelength modulation. The processor system is equivalent to a diffraction spectrometer except that a linear charge-coupled photodetector operating in a delay-and-add m

Acoustooptic spectrum analyzer with time integration utilizing a semiconductor laser and a photodetector based on charge-coupled devices
Autor: V. V. Perepelitsa, N A Esepkina, N. N. Evtikhiev, A P Lavrov, Bondartsev S Yu
Publikováno v: Soviet Journal of Quantum Electronics. 18:542-544
An experimental investigation was made of an interference acoustooptic spectrum analyzer with time integration and a photodetector based on charge-coupled devices. The input signal was provided by time modulation of radiation from a semiconductor las

Reduction of the Parasitical Signal of Circular Polarization on an Antenna of Variable Profile With the Help of a Grating
Autor: N. A. Esepkina, V. Y. Petrunkin, N. S. Soboleva, G. M. Timofeeva, A. V. Reiner
Publikováno v: Symposium - International Astronomical Union. 43:91-93
A method of reducing circular parasitical polarization in the antennas of variable profile with the help of a grating of curved wires is reported. The experimental verification of the method shows that the parasitical signal practically vanishes. It

Time Integrating Acoustooptic Spectrum Analyser
Autor: A. P. Lavrov, V. V. Perepelitsa, N. N. Evtihiev, S. U. Bonclartsev, N. A. Esepkina
Publikováno v: SPIE Proceedings.
The results of the experimental study of several interferometric spectrum analysers with CCD time integration are presented. The input was performed either by the direct time modulation of the semiconductor laser emission or by the modulation carried
