Abstract
A method for reducing or eliminating “Missile Tip-off Effect” (MTE) of a missile ejected from a canister. The method includes: receiving data of desired canister state in response to a launch command. The method further include perform repeatedly until an MTE control criterion is met: (a) receiving, from a sensor associated with the canister, data of measured canister state, and (b) processing the data of the measured canister state and desired canister state, for outputting data indicative of a command to an actuator associated with the canister for modifying at least the angular position of the canister, thereby reducing or eliminating the (MTE) effect.
Claims16
A method for reducing or eliminating “Missile Tip-off Effect” (MTE) of a missile ejected from a canister comprising, by a processor and associated storage:
- a. receiving data indicative of desired canister state in response to a launch command,
- perform repeatedly until an MTE control criterion is met:
- b. receiving, from at least one sensor associated with the canister, data indicative of measured canister state;
- c. processing at least said data indicative of measured canister state and desired canister state, for outputting data indicative of a command to at least one actuator associated with the canister for modifying at least the angular position of the canister;
- thereby reducing or eliminating said (MTE) effect.
The method according to any one of the preceding claims, wherein said measured canister state includes measured missile angle and wherein desired canister state includes desired canister angle.
The method according to any one of the preceding claims, wherein the larger the difference between the desired canister state and the measured canister state, the larger is said command.
The method according to any one of the preceding claims, wherein said measured canister state includes data indicate of remaining flight time of the missile in the canister, such that for the same difference in measured angle or rate vs. desired angle or rate, the shorter the remaining flight time, the larger the command.
The method according to any one of the preceding claims, further comprising modifying on-the-fly said data indicative of desired canister state.
The method according to any one of the preceding claims, wherein at least one of said sensors is fitted on the canister.
The method according to any one of the preceding claims, wherein at least one of said sensors is fitted on the missile.
The method according to any one of the preceding claims, further comprising an array of canisters.
A system for reducing or eliminating “Missile Tip-off Effect” (MTE) of a missile ejected from a canister comprising, a processor and associated storage configured to:
- receiving data indicative of desired canister state in response to a launch command, perform repeatedly until an MTE control criterion is met:
- a. receiving, from at least one sensor associated with the canister, data indicative of measured canister state;
- b. processing at least said data indicative of measured canister state and desired canister state, for outputting data indicative of a command to at least one actuator associated with the canister for modifying at least the angular position of the canister;
- thereby reducing or eliminating said (MTE) effect.
