Measurement of autocorrelation functions in a bi-static incoherent scatter radar
Abstract
The scattering volume and the pulse weighting factor are calculated for a bistatic incoherent radar in order to interpret the autocorrelation function measurements. It is assumed that the ionospheric plasma is uniform within the scattering volume and the receiver impulse response is a delta function. The ionosphere autocorrelation function is then the product of a Fourier transform of the electron cross section for incoherent scatter, the autocorrelation function of the transmitted pulse envelope, and a constant accounting for the antenna gain, range, and transmitted power pulse length. A modified weighting function is defined in terms of the delay and the time of the first sample. Sample calculations are presented for the EISCAT UHF incoherent scatter radar operating at 933 MHz in Norway, with receivers in Sweden and Finland.
