Abstract:
1. A counter-flying object system, comprising: a sensor array that includes at least one active sensor configured to detect and track a flying object upon launch of the flying object and at least two passive sensors; the sensor array is configured to determine the flying object's location and upon launching of a seeker-less interceptor missile also the seeker-less interceptor missile's location and send the flying object's location and the seeker-less interceptor missile's location to a control system, the sensor array is further configured to achieve respective clock synchronization accuracy of at least 1 nanosecond between each two sensors of said array; the control system is configured to generate a mission data including Predicted Interception Point (PIP), a time of launch, interceptor missile separation time and transfer the mission data to an interceptor missile launcher, the control system is further configured to calculate, selectively update and send to said seeker-less interceptor missile, through an uplink communication channel, uplink messages including updated Predicted Interception Point, updated interceptor missile separation time and the location of the seeker-less interceptor missile during flight; the interceptor missile launcher is configured to launch the seeker-less interceptor missile at said time of launch towards said Predicted Interception Point (PIP); the seeker-less interceptor missile includes a separable motor, a warhead, a steering system, a communication system, and a navigation system configured to repeatedly generate navigation data; said seeker-less interceptor missile is configured to selectively utilize said mission data, said uplink messages and said navigation data for separation of said separable motor and generating steering commands to said steering system for guiding the seeker-less interceptor missile toward the updated PIP and activating a fragmentation warhead on or in a vicinity of said PIP when a lethality criteria is met, wherein synchronization is achieved by said control system performing computations based on the following equations: (Equations 1 and 2): wherein samples A provided by a first sensor include: P Φ wherein samples B provided by second sensor include: P Φ and wherein: ρ C—speed of light, B I T F ε ε δt
