Abstract :
The new trends in the interferometry include the use of wide bandwidth systems as a means for accurate angle measuring or enhancing of angle resolution. Ultra wide band (UWB) interferometry with spectral analysis of noise signal is based on the summation of perfectly incoherent noise signals received by two space-apart antennas. This paper demonstrates techniques for more accurate estimation of the angle and the angle velocity of moving targets. Every spectral component of the sum signal oscillates in the current time with Doppler frequency. By measuring of Doppler frequency of these oscillations the angle velocity of moving target is estimated.
