Abstract : The patent relates to a transmitter and receiver filter network suitable for use in an echo-location system, for providing a high-resolution mapping of a distribution of scatterers, and capable of being implemented by simply using transversal filter technology. With a suitable choice of parameters and external transducers, the system may be used as a radar, sonar, or geophysical exploration system.
