WebPulse radar emits short and powerful pulses and in the silent period receives the echo signals. In contrast to the continuous wave radar, the transmitter is turned off before the measurement is finished.This method is characterized by radar pulse modulation with very short transmission pulses (typically transmit pulse durations of τ ≈ 0.1 … 1 µs). WebBecause of this the essential functions of signal processing and echo-integration are first described by reference to the Simrad QM system. A brief description of the main features of the digital units is then given in section 3.3. An echo-integrator receives all signals from the calibrated output of the echo-sounder, see diagram 1 of Figure 24.
