Abstract
This paper presents a technique for estimating the Doppler frequency shift of the probing signal. The technique is based on the use of a signal packet consisting of at least two identical complex signals with “good” autocorrelation properties, and the operation of autocorrelation (“convolution” of the received signal with itself) at the receiver. The results of experimental testing of the technique, carried out on August 17, 2013, are presented. The obtained field data are compared with GPS measurements and algorithms for estimating the Doppler shift.
