Abstract:
A rf receiver includes a multiple echo delay line, a switch, an rf activity detector, and a measurement receiver. A received rf signal initially impinges on the delay line but after a brief delay the detected rf signal actuates a switch, which disconnects the delay line from the input and connects it to the input of the measurement receiver, which receives and processes the multiple signal echos from the delay line.
