Question: How to make a radar simulation on XY Graph?

[uChiron]

Just uncheck the "Erase First" to stop flickering

[LocalDSP]

Couldn't resist either

Friday Night Fun - Now with Sonar Sound (though radar <> sonar).

Is there anyway to remove the scale (numbers), but leave the grid?

Remove the yellow marked wires in "draw polar grids.vi"

Be careful!

You will be modifying a VI in vi.lib. Better to clone off the VI as a new name then make the edits.

A real radar simulation might need an intensity graph, showing the radar echo intensity as a function of direction and distance. You could simulate a 2D world with some objects and given radar reflectivity, the canculate the profile for each direction.

Here's how this could look like. Modify as needed. 😄

(Ships are static but could easily be animated inside the main loop if desired.)

Reminds me to my mil. service time back in the 80's being radar mechanic .. 🙂

The radar was all tube based, designed in the 60's, the deflection unit was mechanically turning around the CRT (in sync with the antenna)

Some more challenges:

Decay time should be longer....

The 'green' line shouldn't  be a line, just random noise on a lower level...

Would be easy to add noise. Decay can be prolonged by subtracting only every n-th iteration. Do you have a video of a real (not Hollywood) old radar screen?

Could also go to U16 for the display but I think 256 shades is plenty. 😄
