 | Realistic weather radar simulation for use with a own PC or in connection
with a FMC
|
|
Based on the Collins WXR2100 weather radar
|
|
Realistic beam (3,5° width) with adjustable tilt (+/-15°) and 160°
angle of view.
|
|
WX and WX+TURB modes and Test image
|
|
10NM up to 320NM range, settable via Keyboard or from PM ND display range |
| Off-sets are available for programming keys/switches (writing/reading
offsets)
|
|
Simulated path attenuation and simulated compensation within 80NM (PAC)
including the PAC ALERT as modelled in the Collins WXR2100
|
|
High cloud formations (thunderstorms, towering cumulus) are divided into
“sub clouds”, to model the different reflections at different altitude
stages
|
|
Simulated ground reflections based on a simple elevation model ! So cloud
reflections can be embedded within ground clutter as in reality.
|
|
Simulation of the real Collins WXR2100 features OFP (over fly protection)
and the GCS (ground clutter suppression).
|
|
You need not to set 3D Clouds, it works in depended of any cloud density or
range settings
|
|
Works together with Project Magenta Navigation displays, so the radar image
can be displayed within them, as in reality !

Some photo's of the SA-WXR running on the PSOne LCD
LCD construction
Using Plexiglas and 4 x 6mm busses to protect the backside of
the LCD screen.
Front panel design
Pushbuttons
Above the mechanism for the push buttons; the left buttons will push directly
on the tactile buttons of the PSOne PCB (brightness + /-). The right buttons
will be used the switch the radar functions OFP and GCS on/off. The switch
contacts are build within
The rods have will be shorted to the right length (as soon as panel is finalised)
Switches
The picture below shows a potmeter with a neutral 'click' in the middle of
the rotation (like the balance in a radio).
We used a basic 10kOhm potmeter assembled in a small mechanism with a small
spring and a small ball, that clicks in a hole in a small cilinder that is fixed
on the potmeter shaft .
The potmeter will be used to set the TILT (from -15 degrees to +15 degrees
with a neutral 0 degrees)
Monitor
I'm using a modified PSOne screen for displaying the weather radar. This
screen is connected to the TV-out connector on the video card
Backside of graphics card with (Left to Right): DVI,
S-Video (tv-out) and VGA.
Computer S-video to TV composite video
If you want to use a VGA output to connect to the PSOne it is possible to
hack the PSOne. I added some links below. Opinions vary if this is worth the
effort. The "Video Output" Quality and the "VGA Output
Quality" seem to come close
