The UK incoherent scatter radar
Radio Science, 1974The UK incoherent scatter system operates in two modes. The monostatic pulsed system has been in operation since 1968, and a summary of the results obtained in this mode is given. The full multistatic CW system has been operating since September 1972 and among the preliminary results are measurements of the total vector of velocity drift.

Incoherent X-Ray Scattering Factors
The Journal of Chemical Physics, 1965Incoherent scattering factors for C, O, Cl, Al, and I are calculated from Hartree—Fock—Slater wavefunctions. Comparison of the values of C and Al with Hartree—Fock values show good agreement. Results for I, which represent the heaviest element for which calculations of this type have been performed, are compared with statistical Thomas—Fermi values.

Incoherent neutron scattering from KDP
Ferroelectrics, 1994Abstract Neutron incoherent scattering experiments over a wide range of energy-momentum space were carried out by utilizing both pulsed and steady neutron sources, in order to investigate the dynamical properties of the protons in KDP (KH2PO4). In the paraelectric phase, no inelastic peaks corresponding to the proton tunneling mode were observed within

Incoherent subharmonic light scattering in isotropic media
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2005Incoherent subharmonic light scattering in isotropic media is a new kind of nonlinear light scattering, which involves single input photon and multiple output photons of equal frequency. We investigate theoretically the dependence of the subharmonic scattering intensity on the hyperpolarizability of molecules and the incident intensity using nonlinear ...

Incoherent Scatter Radar Results
1975Incoherent scattering is the Thomson scattering of electromagnetic waves of very high frequency (e.g., several hundred MHz) by the free electrons in the ionosphere. In any scattering experiment, the received signal is proportional to a spatial Fourier component of the scatterers density (here the electron density); the relevant wave vector k is mainly ...

Incoherent scattering at radio frequencies
Journal of Atmospheric and Terrestrial Physics, 1970Abstract The current status of theory and observations of incoherent scatter from the ionosphere are discussed. Some examples of the more important scientific advances which have resulted from incoherent scatter measurements are given. Comparisons of scatter data with data obtained by other techniques shows good agreement in some, but not all cases ...

Techniques for Incoherent Scatter Communication
IEEE Transactions on Communications, 1962Special radiometric-detection procedures are appropriate when communication signals are severely distorted by a rapidly fluctuating, noisy, time-dispersive channel. This paper presents a performance analysis of some digital communication techniques that can be used when most other techniques fail. Error-probability expressions are derived and evaluated
