Radar operations in one or more nodes may be controlled, with the controlling including applying one or more measures for improving radar angular resolution for at least one radar deployed on one of the one or more nodes, with the improving of radar angular resolution entailing increasing radar angular resolution for the at least one radar relative to an identical radar operated in identical conditions. The one or more measures comprise fusing radar data with data from other data sources, movement of radar platforms, use of multiple radars for triangulation, use of multiple nodes moving in formation, and creating features or distortions of antenna beams. The one or more nodes may be aerial drones. ## Claims ### Claim 1 A method for controlling radar operations in one or more nodes, the method comprising: applying one or more measures for enhancing radar angular resolution for at least one radar deployed on a node of the one or more nodes, wherein the one or more measures comprise movement of radar platforms. ### Claim 2 (depends on 1) The method of claim 1, further comprising, when using movement of radar platforms: obtaining first radar data from the at least one radar for a target at a first position; moving the node comprising the at least one radar to a second position that is different from the first position; and obtaining second radar data from the at least one radar for the target at the second position, wherein the first position and the second position are known positions at the time of obtaining the first and second radar data. ### Claim 3 (depends on 2) The method of claim 2, further comprising determining location information of the target based on the first radar data and the second radar data. ### Claim 4 (depends on 3) The method of claim 3, wherein the at least one radar comprises a phased array antenna. ### Claim 5 (depends on 4) The method of claim 4, further comprising adjusting an antenna beam of the phased array antenna based on the determined location information of the target. ### Claim 6 (depends on 1) The method of claim 1, wherein the node of the one or more nodes is an aerial drone. ### Claim 7 (depends on 6) The method of claim 6, wherein the aerial drone is autonomous. ### Claim 8 A method for controlling radar operations in one or more nodes, the method comprising: applying one or more measures for enhancing radar angular resolution for radars deployed on two or more nodes, wherein the one or more measures comprise use of the radars deployed on two or more nodes for triangulation. ### Claim 9 (depends on 8) The method of claim 8, further comprising, when using the radars deployed on the two or more nodes for triangulation: obtaining first radar data for a first radar on a first node of the two or more nodes at a first position, and obtaining second radar data for a second radar on a second node of the two or more nodes at a second position; wherein the first position is different from the second position and the first position and the second position are known positions at the time of obtaining the first and second radar data. ### Claim 10 (depends on 9) The method of claim 9, wherein the first radar and the second radar each comprise a phased array antenna. ### Claim 11 (depends on 10) The method of claim 10, wherein the first node and the second node are aerial drones. ### Claim 12 (depends on 11) The method of claim 11, wherein the aerial drones are autonomous. ### Claim 13 A method for controlling radar operations in a plurality of nodes, the method comprising: applying one or more measures for enhancing radar angular resolution for a first radar deployed on a first node of the plurality of nodes, wherein the one or more measures comprise use of the plurality of nodes moving in formation. ### Claim 14 (depends on 13) The method of claim 13, further comprising, when using the plurality of nodes moving in formation, coordinating radar operation for the first radar deployed on the first node and a second radar deployed on a second node of the plurality of nodes. ### Claim 15 (depends on 13) The method of claim 13, further comprising, when using the plurality of nodes moving in formation, using passive detection via the first radar and a second radar deployed on a second node of the plurality of nodes. ### Claim 16 (depends on 13) The method of claim 13, further comprising, when using the plurality of nodes moving in formation, sharing target information between the first node of the plurality of nodes and a second node of the plurality of nodes. ### Claim 17 (depends on 14) The method of claim 14, wherein the first radar and the second radar each further comprise a phased array antenna. ### Claim 18 (depends on 17) The method of claim 17, wherein the first node and the second node are aerial drones. ### Claim 19 (depends on 18) The method of claim 18, wherein the aerial drones are autonomous. ### Claim 20 A node configured for operating in a network comprising a plurality of nodes, the node comprising: a radar configured for detection of objects in a vicinity of the node; and one or more circuits configured to apply one or more measures for enhancing radar angular resolution for the radar, wherein the one or more measures comprise one or more of: movement of the node, use of multiple nodes for triangulation, and use of multiple nodes moving in formation.
