This was an automatic guidance system algorithm for atmospheric optical laser communication systems.
Here's a picture of what https://www.mql5.com/go?link=http://www.interpolitex.rasu.ru/index.php?catalog=1&org=1584&id=1775 looks like.
It was necessary to converge 2 counter beams to one point in minimum time to provide 2 way communication.
The distance between the devices was about 3-4 km and the current positions of the transmitting heads to inform the receiving side
was simply impossible.
Yes, it's a practical problem. But it's different. We have rays here, not dots.
I do not understand what it means to bring the rays to a point. Should I direct the rays to one point so that they intersect, or should I direct them strictly against each other?
Это был алгоритм системы автоматического наведения для систем атмосферной оптической лазерной связи.
Тут картинка, как выглядит https://www.mql5.com/go?link=http://www.interpolitex.rasu.ru/index.php?catalog=1&org=1584&id=1775
Нужно было за минимальное время свести 2 встречных луча в одну точку для обеспечения 2 сторонней связи.
Между приборами было порядка 3-4 км и текущие положения передающих головок сообщить приёмной стороне
было просто невозможно.
Oops, neighbour.
We used to go to your pool before New Year's, the "Screen".
The right thing to do is, of course, against each other. Just as a consequence, they converged on one point.
But a reception at an acceptable angle was also possible.
Упс, сосед
А мы в ваш бассейн ходим, ходили до нг, "Экран"
I was just showing a picture )
And how long does it take for them to actually converge according to your algorithm?
A reconnaissance plane flies in a circle of 10 km radius, centered at point A, at 1000 km/hour. At some point, a missile with the same speed as the plane is fired from point A, and is steered so that it is on the straight line connecting the plane with point A the whole time. In what time will it catch up with the plane? 69
20 sec to 3-5 min. Depends on the accuracy of the initial setting
But I don't think it's ever been more than 5
Up to five minutes of rays? Wow. I thought it was a lot faster.
И за какое время они реально сводятся по твоему алгоритму?
Самолет-разведчик летает по кругу радиуса 10 км, с центром в точке А, со скоростью 1000 км/час. В некоторый момент из точки А выпускают ракету с той же скоростью, что самолет, и управляется она так, что все время находится на прямой, соединяющей самолет с точкой А. Через какое время она догонит самолет?
36 seconds ?
До 5 минут лучи сводятся? Ух ты. Я думал, все намного быстрее.
Depends on the initial installation.
