The first coherent accumulation was carried out, which increased the signal-to-noise ratio to 11.57 dB. However, it failed to reach the 14.24 dB signal-to-noise ratio of the LFM echo signal. This was due to the certain loss in coherent accumulation. After performing a second parallel accumulation on the signals received by the 8 antennas, the signal-to-noise ratio of the echo signal increased to 75.21 dB.
