摘要： The presently disclosed subject matter includes a method, apparatus and computer storage device for reducing dispersion of a rocket caused by jet-stream misalignment, the rocket comprising a rocket engine. Information indicative of a division of total operation time of the rocket engine into a first time period and a second time period is obtained; wherein an impulse which is generated during the first time period is at least approximately the same as an impulse generated during the second time period; a period of time which equals to the first time period starting from time of activation of the rocket engine is measured; upon termination of the period of time, the rocket is rotated around the rocket's longitudinal axis; and the angle of rotation measured; and the rotation is stopped once a 180° rotation is completed.

摘要： The presently disclosed subject matter includes a laser system and a respective method of detecting a signal reflected from a target illuminated by a modulated CW light source configured to generate a modulated laser signal at a predefined modulation frequency. A signal comprising true laser signal portions reflected from said target, and noise is received; the signal is filtered for selecting laser signal portions at a modulation frequency band; and the true signal portions in the signal are detected, if the energy at the modulation frequency band is greater than a given threshold.
