Pulse compression compression is very sensitive to frequency changes due to the Doppler effect if that change is larger than formula_86. Pulse compression Pulse compression is a signal processing technique commonly used by radar, sonar and echography to increase the range resolution as well as the signal to noise ratio. This is achieved by modulating the transmitted pulse and then correlating the received signal with the transmitted pulse. The simplest signal a pulse radar can transmit is a sinusoidal-amplitude pulse, formula_1 and carrier frequency, formula_2, truncated by a rectangular function of width, formula_3. The pulse is transmitted periodically, but that is not
