摘要:
Optoelectronic apparatus (2) for assisting an operator in determining the shooting attitude to give to a hand-held grenade launcher (1) so as to strike a moving target (k) comprising an electronic processing unit (9) configured so as to: measure the pitch angle (α pitch (t ci ) ) and the heading angle α heading (t ci ) ) of the grenade launcher (1) and the distance (Dist target (t ci ) ) of the target (k) when the grenade launcher (1) is moved by the operator during the pointing of the moving target (k), determine position data (XT(ti), YT(ti), ZT(ti)) indicative of the positions of the moving target (k), determine a future impact time (t imp ) of the grenade on the target (k) on the basis of position data (XT(ti), YT(ti), ZT(ti)) and of data indicative of the ballistics of the grenade, determine a shooting attitude of the target (k) on the basis of the impact time (t imp ), measure the pitch angle (α pitch (t act ) ) and heading angle (α heading (t act ) ) indicating the attitude imparted to the grenade launcher (1) by the operator, compute a pitch difference (Δα pitch ) between the shooting pitch angle (αf pitch ) and the pitch angle (α pitch (t act ) ) measured and a heading difference (Δα head ) between the shooting heading angle (αf head ) and the heading angle (α head (t act ) ) measured, communicate to the operator the variation of pitch and/or heading to be given to the grenade launcher (1) so that the pitch (Δαpitch) and/or heading (Δα head ) difference is zero.
摘要:
A LASER rangefinder (2) comprising an emitter stage (4) to emit LASER pulses, a receiver stage (5) to generate electrical distance signals (SD) based on the LASER pulses received, an optical splitter (7) and a processing unit able to: sample each electrical distance signal (SDi) to determine a first vector (PV) containing first sample values (pvi); filter the first vector (PV), through a digital low-pass filter, to determine a second vector (SV) containing second sample values (svi); determine a third vector (TV) containing third sample values (tvi) determined by subtracting the second sample values (svi) from the corresponding first sample values (pvi); calculate a standard deviation (σ) on the basis of the third sample values (tvi); calculate a plurality of detection thresholds (SR(i)) based on the standard deviation (σ), the second sample values (svi) and a predetermined coefficient (oi(i)); compare each first sample value (pvi) with a corresponding detection threshold (SR(i)); and calculate the target distance (D) based on the result of the comparison.
摘要:
An apparatus for determining the attitude angles of a weapon ( 1) comprising a number of accelerometers for measuring the components (A x , A Y , A z ) of the acceleration of the weapon (2) along the axes (X BODY , Y BODY , Z BODY ) of a first reference system (∑ BODY ) integral with weapon (2); a number of gyroscopes ( 8 ) configured in such a way to measure the components of the angular speed (G x , G y , G z ) of the weapon along the axes (X BODY, Y BODY , Z BODY ) of the reference body (∑ BODY ); and a processing unit (10) configured to compute a number of actual attitude angles of the weapon (Prc, Rro, Hrd) under dynamic conditions based on the components of the angular speed (GX, GY, GZ ); determine a number of static attitude angles of the weapon (Psc, Rso, Hsd) under static conditions of the weapon based on the components of the acceleration (A x , A Y , A z ); correct the components of angular speed (G x , G y , G z ) according to static attitude angles (Psc, Rso, Hsd) and to the actual attitude angles (Prc, Rro, Hrd).
