Abstract

The pulse communication system includes a plurality of pulse repeaters 10 for receiving and transmitting pulse signals. Each of the pulse repeaters include a frequency controller 22 for selecting one of a sequence of transmit and receive frequencies. The frequency controller 22 causes the transmit and receive frequency to change after the reception of each pulse in order to receive and transmit the next pulse on another frequency.

Claims

1. A pulse communication system comprising:

a plurality of pulse repeaters for receiving and transmitting pulse signals, each of the repeaters including frequency control means for selecting one of a sequence of transmit and receive frequencies of the repeater, the frequency control means changing the transmit and receive frequency in response to the reception of any pulse in order to receive and transmit the next pulse on another frequency.

2. A pulse repeater comprising:

receiving means for receiving pulse signals,

detecting means connected to the receiving means for detecting the presence of a pulse signal,

transmitting means connected to said detecting means and responsive thereto for transmitting a pulse signal upon detection of the pulse signal, and

frequency control means operatively selecting one of a sequence of operating frequencies of the receiving and transmitting means, the frequency control means selecting the operating frequency of the transmitting means to transmit each received pulse on the frequency on which it is received and selecting a different receive frequency in response to the reception of each pulse.

3. A pulse transceiver comprising:

receiving means for receiving pulse signals,

transmitting means for transmitting pulse signals, and

frequency control means for selecting the operating frequency of the receiving and transmitting means, the frequency control means changing the operating frequency of the receiving means in response to the reception of each pulse and changing the operating frequency of the transmitting means after the transmission of each pulse.

4. A pulse transceiver comprising:

receiving means for receiving pulse signals,

transmitting means for transmitting pulse signals, and

frequency control means for selecting the operation frequency of the receiving and transmitting means, the frequency control means changing the operating frequency of both, the transmitting and receiving means in response to the reception of each pulse and after the transmission of each pulse.
