F-35 AAQ-40 EOTS/electro-optical targeting system.

It functions as a passive detection and tracking system that combines Forward looking Infrared (FLIR) and Infrared Search and Track (IRST) for targeting and tracking air to air and air to ground targets.

RPD Oscar has passed away. Retiring years ago as a much loved family pet. Oscar was an active & passive detection drugs dog (think club queues), he was the first dog in the country to win a WOW award & only the second in the world at the time. Oscar had even been on the BBC!

Aircraft detection before radar, 1917-1940.
Acoustic location was used from mid-WW1 to the early years of WW2 for the passive detection of aircraft by picking up the noise of the engines.

Horns give both acoustic gain and directionality; the increased inter-horn spacing increases the observer’s ability to localize the direction of a sound.

Εικόνα Ινδικού Α/Φ Rafale (F3R + ISE). Δυστυχώς, το IRST δεν το έχω δει στα ελληνικά Rafale μέχρι τώρα. Ευελπιστώ η νέα παρτίδα να το περιλαμβάνει, καθώς προσδίδει το πλεονέκτημα με passive detection & lock on σε μεγάλες αποστάσεις.

Let's try again.
For those confused about what the new passive detection for stealth is,
This is what 30 units looks like.
The entirety of this circle, standing in the middle, will be how far you can see invis characters next patch.
I think is should be 40

VERA, passive detection system, which uses the Time Differential of Arrival Principal (TDOA). Does this thing actually work or is it a scam?? I have no idea. Anyone know?

A reminder that passive detection dogs will be deployed at both home & away turnstiles tomorrow. Pyrotechnics are illegal and harmful, which could result in prosecution or worse, serious injury. Don’t take the risk! Notts County FC (P) Mansfield Town FC

4-Acoustic location is a method of determining the position of an object or sound source by using sound waves. Acoustic location was used from mid-WW1 to the early years of WW2 for the passive detection of aircraft by picking up the noise of the engines.

Ray’s problem is not the one I am working on.

Ray wants to detect weak incoming far-field gravity waves using entangled pairs of electron spins and entangled pairs of photons.

This is the PASSIVE DETECTION OF GRAVITY FAR FIELD.

In contrast, the WARP DRIVE PROBLEM is the ACTIVE…

A Chinese operational J-11BG aircraft can be seen with new pylons, able to carry PL-15 long range BVR missile.
J-11BG is an upgraded variant of J-11 series jets equipped with AESA radar, better avionics, better passive detection systems.

'our enemies also have stealth...'

Cool. That's why we have the AN/APG-85 in development for the Blk IVs and EO/IR pods for passive detection.

Do you even know what any of this means Elon Volo 🇮🇱? Because you've been pretty ignorant so far.
