METHOD FOR DETERMINING THE IMPACT POINT OF A PROJECTILE FIRED AT A TARGET ABOVE SEA SURFACE, AND RADAR SYSTEM IMPLEMENTING SUCH METHOD

摘要

There is disclosed a method for determining the impact point of a projectilefired at a target (15) tracked by use of aradar antenna (11) through a dedicated antenna beam, the method beingcharacterized in that it comprises at least a step of measuringthe range and bearing of the projectile based upon the use of said radarantenna (11) and said dedicated antenna beam, a step ofDoppler filtering distinguishing the projectile measurements from the trackedtarget (15) and sea clutter measurements, and a step ofdetermining the projectile trajectory (131) from a plurality of range andbearing measurements performed at successive instants of time(t i), and a step of determining the impact point of the determined projectilebased upon the projectile trajectory (131). The currentinvention can be applied to splash spot location prediction and miss distanceindication.
