Abstract
A method for mitigating interference among a plurality of radar sets utilizes the steps of: determining the direction in which a radar antenna is pointing; selecting one of a plurality of different non-interfering radar signals based upon the direction that the radar antenna is pointing, each different non-interfering radar signal beam dedicated to a particular direction of the radar antenna; and utilizing the selected radar signal. Radar antennae pointed toward one another do not interfere with one another since they are both using different non-interfering radar signals.

A method for mitigating interference among a plurality of radar sets, said method comprising the steps of:
- a) determining the direction in which a directional radar antenna is pointing;
- b) selecting one of a plurality of different non-interfering radar signals based upon the direction that the radar antenna is pointing, each different non-interfering radar signal being dedicated to a particular direction of the radar antenna;
- and
- c) utilizing the selected radar signal;
- d) wherein radar antennae pointed toward one another do not interfere with one another since they are both using different non-interfering radar signals.
A radar system for mitigating interference among a plurality of radar sets, each radar set comprising:
- a) a directional antenna;
- and
- b) a direction sensor for sensing the orientation of said antenna;
- c) a signal selector for selecting one of a plurality of different non-interfering radar signals based upon the direction that the radar antenna is pointing, each different non-interfering radar signal being dedicated to a particular direction of the radar antenna;
- and
- d) a radar transceiver for transmitting the selected radar signal through said direction antenna and for receiving the return radar signal through said directed antenna;
- e) wherein two such radar antennae pointed toward one another do not interfere with one another since they are not pointed in the same direction and thus are both using different non-interfering radar signals.
A radar set comprising:
- a) a directional antenna;
- b) an electronic compass coupled to said directional antenna for determining the compass bearing thereof;
- c) a microprocessor responsive to said electronic compass for selecting one of a plurality of different orthogonal radar signals;
- and
- d) an orthogonal waveform signal generator for generating the selected orthogonal radar signal;
- e) a radar transceiver for transmitting and receiving the selected orthogonal radar signal via said directional antenna;
- f) wherein two such radar antennae pointed toward one another do not interfere with one another since they are not pointed in the same direction and thus are both using different non-interfering radar signals.
