“…consists of the samples of the digitalized echo-signal. As the echo-signal is produced by reflection of the probe signal from the surface of some object, the echo-signal is a diminished copy of the probe signal of the radar transmitter [3], [5], [6]. Due to this reason, the samples (2) are complex numbers, presenting the complex envelopes of the elementary phase symbols (or chips) with duration ππ ππβ , forming the probe signal.…”
