Abstract
A digital telemetry device includes synchronous counters monitored by a clock. The counters are connected, on the one hand, to two comparators and, on the other hand, to a buffer memory. The comparators generate a telemetry mark which makes it possible to form a tracking window. The buffer memory stores or transmits the value of the counters whenever it receives an echo presence signal. The comparators work with most significant bits (MSB) to generate the telemetry mark, whilst the buffer memory works with least significant bits (LSB) which make it possible to determine the position of the target in relation to the center of the telemetry mark, for example by the use of a "complement-on-two" code.
Claims14
A digital telemetry device, comprising:
- clock means for providing a clock signal;
- counting means, synchronized by said clock signal, for providing a count signal including most significant bits (MSB) and least significant bits (LSB);
- comparator means for receiving said MSB and providing a telemetry signal corresponding thereto;
- and
- ranging means adapted for receiving a target echo detection signal and said LSB, and for providing a range signal corresponding to a range to the target.
A digital telemetry device, comprising:
- counting means, comprised of ECL technology, for providing a count signal;
- comparator means, comprised of ECL technology, for receiving said count signal and providing a telemetry signal corresponding thereto;
- ranging means adapted for receiving a target echo detection signal and said count signal, for providing a range signal corresponding to a range to the target, said ranging means including a memory register comprised of TTL technology;
- and
- interface means for interfacing said TTL memory means and said ECL counting means.
