Share My Creation UltraSonic radar and Missile defense system

Hi
This system in include 2 part.
part 1 is a ultrasonic radar system include one ultrasonic module and one servo motor.
This system detects targets at a distance of less than 4 meters.
part 2 is a rocket platform with 3 rocket.

when radar detect a target , missile system lock on the nearest target .
If the target does not run away in 5 seconds, one of the missiles will be fired.

in normal case green led turn on in top of Truck and in war case red led and alarm turn on .

Hi Vali,
Would you share the project files? (sch and b4r code)? Thanks

How does it get the two angles (vertical and horizontal) to target with only one servo?

Hi
I am glad that this project has been noticed
If you want photos or videos from the project, give me an email address and I will send them
I will be happy if you visit my telegram chanel with address t.me/basic_for_arduino

hi.
I sent it in above post .

Hi.
my radar only rotates in one direction.

 

[agraham]

my radar only rotates in one direction

Just like the Bloodhound missile launcher did

I'm going to guess that the Bloodhound's radar had some way of electronically determining elevation, or perhaps by moving the feed horn.

If the @Vali-khandangoll radar had more than one transmitter or receiver, with slightly different elevation angles, I'd be even more impressed than I already am.

A project for a rainy day. ?

Or perhaps have a single transmitter, and three receivers place triangularly around it: if you have access to the raw ultrasonic return and sample it fast enough, perhaps you might be able to locate the target in azimuth and elevation using phase / time difference.

 

[agraham]

I said launcher, not radar. The Bloodhound had a fixed elevation launcher that it cleared with a brutal more than 30g acceleration on launch. Until the boosters peeled off the missile dish was locked in position to survive the launch having been pre-positioned by the launch computer so that when the dish unlocked it was pointing at the predicted target position.

Source : I worked on the RAFs Bloodhound Mk2 launch simulator.

Lol I would have liked to be present for the first launch when they discovered that little design issue.

Though it looked to me like the radar was separate to the launcher, which'd make sense in that one radar could serve multiple launchers.

As with the "caution: contents may be hot" warnings on McDonald's hot apple pies, perhaps the authors of the procedures for the Bloodhound system initially thought:

hmm, do we need to state the obvious about keeping clear near and behind a launching missile...

 

[agraham]

You misunderstand. The dish was deliberately mechanically locked during launch because an anti-anti-missile precaution in the missile guidance meant it couldn't hold target lock during launch because of the large and rapidly changing Doppler effect it would see on the target returns. Hence the need to pre-point the dish so the missile saw the target when the dish unlocked after shedding the boosts.

Your opinion is absolutely correct, but this is an educational project like a toy
