IMPACT POINT OBSERVATION SYSTEM

PROBLEM TO BE SOLVED: To improve correction precision of a firing direction of shooting after an impact point error is provided and to improve the hit probability of a cannonball to a shooting target by providing a more accurate impact point error by an impact point observation device.SOLUTION: Precision of various cannonball motion elements are improved by evaluating observation values of a cannonball and removing an observation value having been affected by a multipath and a sea clutter so as to suppress an error of an impact point position, thereby improving prediction precision of an impact point error. A cannonball observation value is evaluated by weighting differences and angle discrete components of the cannonball observation value and various cannonball motion elements, and S/N, respectively.SELECTED DRAWING: Figure 1 【課題】弾着観測装置において、より正確な弾着誤差を提供することで、弾着誤差の提供を受けた後の射撃における発砲方向の修正精度を改善し、射撃目標への砲弾の命中率を向上させる。【解決手段】砲弾の観測値を評価し、マルチパスやシークラッタの影響を受けた観測値を取り除くことで、砲弾運動諸元の精度を向上し、弾着位置の誤差を抑え、弾着誤差の予測精度を向上する。砲弾観測値は、砲弾観測値と砲弾運動諸元の位置の差分や角度ディスクリ成分、Ｓ／Ｎをそれぞれ重み付けすることによって評価する。【選択図】図１
