An active phased array Doppler sodar with distributed low peak power transmit modules requires pulse compression to provide high sensitivity and fine range resolution. A long transmitted pulse, however, has accompanying problem of near range blind zone. A pulse compression Doppler sodar transmits coded long pulse and compresses the echo-signal resulting in fine range resolution. Barker-coded pulses with matched filter were examined in relation to uncompressed pulses to determine the performance and benefits of pulse compression. The pulse compression technique reduces the peak transmitted power compared to the classical transmission for the given range. The technique also permits the suppression of sidelobes to levels that are acceptable for operational and research applications. I.
