1. A method for transmitting data utilizing transmitted radar pulses, said method comprising:
- determining a pulse repetition interval for radar transmissions;
providing a first radar pulse for utilization as a reference pulse;
providing a second radar pulse based on the pulse repetition interval, a position of the second radar pulse with respect to the pulse repetition interval and the first radar pulse indicative of data to be provided to an intended receiver; and
determining a number of potential time slots in which the second radar pulse can occur based on a range of the radar.

Abstract
A method and system are disclosed where transmitted radar pulses are utilized for both a radar sensing function and for data communications. The data communications are performed in a manner that is simultaneous and transparent to the radar sensing function, in terms of non interference or interruption. The method and system are applicable to data communications between multiple pulsed radar devices as well as radar devices that are capable of receiving pulsed transmissions and transmitting continuous wave transmissions.

7. A radar altimeter comprising:
-
a transmitter; and a radar processor configured to receive data from a controller, said radar processor configured to cause said transmitter to transmit radar pulses at a pulse repetition interval where a position of a second radar pulse with respect to the pulse repetition interval and a first radar pulse is determined based on the data received from the controller; wherein said radar processor is configured to determine a number of time slots during which a second radar pulse can be transmitted based on a range of said radar altimeter. - View Dependent Claims (8, 9, 10, 11)
