A test and analysis system for threat evaluation and sensor/weapon assignment algorithms, enabling interoperability to be tested and analyzed fast and effectively, comprising - at least two threat evaluation and sensor/weapon assignment algorithm operating units which are adapted such that they will operate any threat evaluation and sensor/weapon assignment algorithm, - at least one simulation and analysis unit which is adapted such that it will form an area, in which threat evaluation and sensor/weapon assignment algorithms will be operated, as a virtual scenario by forming an air picture in accordance with data it receives, - at least one external communication unit which is in communication with the simulation and analysis unit; which can communicate correspondingly with a threat evaluation and sensor/weapon assignment algorithm operating unit; which is adapted such that it will transfer a current scenario information to the threat evaluation and sensor/weapon assignment algorithm operating unit when it is necessary and transfer engagement results to the simulation and analysis unit by taking them back, and - at least one communication unit which is in communication with the simulation and analysis unit, and which is adapted such that it will transfer the scenario formed by, communicating with at least one client corresponding to a weapon operator or a commander in the simulation to the client if it is authorized and will receive data through the client if it is authorized where the client presents the engagements for approval, enable to make new engagement/engagement suggestion/engagement cancel record or scenario change, - the simulation and analysis unit which is adapted such that it will update the scenario data in real-time by using data received from the threat evaluation and sensor/weapon assignment algorithm operating units and engagement approval/refusal or manual engagement/engagement suggestion/engagement cancel data received from the client. - at least two threat evaluation and sensor/weapon assignment algorithm operating units which are adapted such that they will operate any threat evaluation and sensor/weapon assignment algorithm, - at least one simulation and analysis unit which is adapted such that it will form an area, in which threat evaluation and sensor/weapon assignment algorithms will be operated, as a virtual scenario by forming an air picture in accordance with data it receives, - at least one external communication unit which is in communication with the simulation and analysis unit; which can communicate correspondingly with a threat evaluation and sensor/weapon assignment algorithm operating unit; which is adapted such that it will transfer a current scenario information to the threat evaluation and sensor/weapon assignment algorithm operating unit when it is necessary and transfer engagement results to the simulation and analysis unit by taking them back, and - at least one communication unit which is in communication with the simulation and analysis unit, and which is adapted such that it will transfer the scenario formed by, communicating with at least one client corresponding to a weapon operator or a commander in the simulation to the client if it is authorized and will receive data through the client if it is authorized where the client presents the engagements for approval, enable to make new engagement/engagement suggestion/engagement cancel record or scenario change, - the simulation and analysis unit which is adapted such that it will update the scenario data in real-time by using data received from the threat evaluation and sensor/weapon assignment algorithm operating units and engagement approval/refusal or manual engagement/engagement suggestion/engagement cancel data received from the client.
