An interceptor fitted with a target tracker unit, that includes passive infrared tracker capable of sensing infrared radiation (IR) emitted from a flying target and being responsive to the sensed IR radiation, for generating a succession of Line of Sight (LOS) and/or LOS rates signals that are stored in a database. Self state means capable of providing a succession of interceptor's self state data. Electro-magnetic range finder that includes a transmitter assembly for transmitting pulsed radiations and receiver assembly for receiving reflections that surpasses adjustable detection threshold. The electro-magnetic finder is configured to operate at first detection threshold for receiving reflections of relatively low magnitude, and storing the reflections in the database. A target reflection detection module communicating with the database, for detecting target reflections from among those stored in the reflection database. Estimator that includes range-based target estimator for calculating target state estimations on the basis of detected target reflections, the LOS measurements and self stage data, thereby facilitating early steering of the interceptor for duly homing said interceptor onto the target.
