The signal is acquired through the dipole antenna. An altitude-dependent number of echoes (of the order of hundred) is collected in a single batch. Doppler processing adds a delay to the samples of each echo, and then sums the samples so as to allow the constructive sum of the signal component coming from a desired direction. Each coherent sum of the echoes is called a synthesized filter: this mode produces 3 filters for every frequency."
