Abstract

In this paper we describe and investigate an acoustooptic system capable for detecting and simultaneously determining both the frequencies and directions of several RF sources with short transmission time. Test measurements of the system have been carried out both in laboratory and real environment. Correction of aberrations of the optical system, correction of the frequency- phase difference characteristics of the antenna array, digital filtering of the output intensity distribution, spurious signal suppression, distinguishing CW and hopping signals; and improving the hopping signal resolution using histograms have been demonstrated. High angular resolution of 1 - 2° and frequency accuracy of < 100 kHz for both CW and hopping signals in a relatively broad frequency range have been achieved.
