System and method of generating target information for a multi-radar target simulator
A system for generating target information for a multi-radar target simulator includes: a modelling unit configured to generate a plurality of objects so as to be located within a plurality of radar detection ranges of a front radar sensor; an object arranging unit configured to arrange the plurality of objects located in each of the plurality of radar detection ranges in a distance order and select at least two objects among the plurality of arranged objects based on an order close to the front radar sensor and the same travelling direction; and a simulator control unit configured to select at least two objects as targets from the at least two objects selected by the object arranging unit as targets and control a multi-radar target simulator by using information about said at least two selected targets.
1 . A system for generating target information for a multi-radar target simulator, the system comprising:
a modelling unit configured to generate a plurality of virtual objects so as to be located within a plurality of radar detection ranges of a front radar sensor;
an object arranging unit configured to arrange the plurality of virtual objects located in each of the plurality of radar detection ranges in a distance order and select at least two virtual objects among the plurality of arranged virtual objects based on an order close to the front radar sensor; and
a simulator control unit configured to select at least two virtual objects as targets from the at least two virtual objects selected by the object arranging unit and control a multi-radar target simulator by using information about the at least two selected targets,
wherein the object arranging unit is further configured to select the at least two virtual objects based on whether a traveling direction of virtual objects, among the plurality of virtual objects, is the same as a traveling direction of a vehicle equipped with the front radar sensor.
2 . The system of claim 1 , wherein the plurality of radar detection ranges includes a short-range radar detection range and a long-range radar detection range.
3 . The system of claim 2 , wherein the object arranging unit is further configured to arrange the plurality of virtual objects located in the short-range radar detection range in an order of distance and select at least two virtual objects among the arranged virtual objects based on an order close to the front radar sensor,
wherein the object arranging unit is further configured to arrange the plurality of virtual objects located in the long-range radar detection range in the order of distance and select at least two virtual objects among the arranged virtual objects based on an order close to the front radar sensor, and
wherein the object arranging unit is further configured to combine the selected virtual objects in the short-range radar detection range or the long-range radar detection range and re-arrange the combined virtual objects in the order of distance.
4 . The system of claim 2 , wherein the object arranging unit is further configured to combine the selected virtual objects in the short-range radar detection range or the long-range radar detection range and re-arrange the combined virtual objects in the order of distance.
5 . The system of claim 4 , wherein when there are overlapping objects among the re-arranged virtual objects, the object arranging unit removes an overlapping virtual object among the overlapping virtual objects.
6 . The system of claim 4 , wherein the object arranging unit is configured to select at least two virtual objects among the re-arranged virtual objects based on the order close to the front radar sensor.
7 . The system of claim 1 , wherein the simulator control unit is further configured to assign target information at a location closest to the front radar sensor among the at least two target information to a first simulator control signal and assign the remaining target information to a second simulator control signal.
8 . The system of claim 7 , wherein the simulator control unit is further configured to compare previous target information and current target information of each target respectively assigned to the first simulator control signal and the second simulator control signal, and
when a relative positional order of the target information assigned to the first simulator control signal and the second simulator control signal crosses, the simulator control unit maintains a previous assignment by cross-assigning the current target information to the simulator control signal identically to the previous target information.
