Russia, China and the USA will have ultra-high resolution photonic radar on future planes to spot and target stealth fighters. Russia has started to invest in military applications of photonic radar technology. The Pentagon has a lead with photonic radar technology. The Pentagon has several photonics-based technology development program underway for radars, signals intelligence and other applications.
It is believed photonic radar would provide the ability to detect stealth fighters at longer ranges perhaps as far as 300 miles.
Photonic radar would also be small and light enough for drones.
Real-time and high-resolution target detection is highly desirable in modern radar applications. Electronic techniques have encountered grave difficulties in the development of such radars, which strictly rely on a large instantaneous bandwidth. In this article, a photonics-based real-time high-range-resolution radar is proposed with optical generation and processing of broadband linear frequency modulation (LFM) signals. A broadband LFM signal is generated in the transmitter by photonic frequency quadrupling, and the received echo is de-chirped to a low frequency signal by photonic frequency mixing. The system can operate at a high frequency and a large bandwidth while enabling real-time processing by low-speed analog-to-digital conversion and digital signal processing. A conceptual radar is established. Real-time processing of an 8-GHz LFM signal is achieved with a sampling rate of 500 MSa/s. Accurate distance measurement is implemented with a maximum error of 4 mm within a range of ~3.5 meters. Detection of two targets is demonstrated with a range-resolution as high as 1.875 cm. We believe the proposed radar architecture is a reliable solution to overcome the limitations of current radar on operation bandwidth and processing speed, and it is hopefully to be used in future radars for real-time and high-resolution target detection and imaging.
Chinese researchers have proposed and demonstrated a photonics-based real-time high-resolution radar applying optical signal generation and de-chirp processing within a compact configuration. The LFM signal generated by optical frequency quadrupling has a very large bandwidth that is required in a high-resolution radar. Besides, photonic de-chirping of the reflected echoes avoids the use of electrical frequency conversion and high-speed ADCs, making it possible for real time processing of a broadband signal in radar receivers. Performance of the proposed method is investigated through an established radar operating at K-band with an 8-GHz bandwidth. The experimental results confirm the feasibility and good performance of the proposed radar scheme, which is a promising solution for real-time ultra-high-range-resolution target detection.

I love how you resent the reality that Musk, BFR, and asteroid mining are and are about good things that will happen. ” You mean BS phantasmagoria.

Photonic radar? Is there a more nonsensical term? Radar works with radio waves and not visible light. Depending how you look at it it’s paradoxical or meaningless, because radio waves are also photons. So what would this be? A camera? Wow…

It’s just fun to tease you starry-eyed types who always talk about what should be instead of trying to understand and work with what is.

So you would rather China and Russia completely overrun us? They certainly are not going to stop just because you want to play nice.

On the other hand, this is the scanner they use on startrek… Maybe readers can get behind it if the right keywords are dropped like “BFR” or “Musk” or “Asteroid mining”.

Well well another 100 billion dollar military system being developed. Then DOE just gave out a huge 40 million to just one company to push MSR technology forward. Yep saving the planet and stopping future wars or massively funding the next round of military industrial complex expansion seems to be an easy decision for the best government that industry can buy.

At the end of the day it is the radar on the missile that is important. Can the radar on the missile lock onto a stealth aircraft and guide the missile in for a hit.

Photonic Radar – sounds like Sonic Sonar or Wet Water
I think they mean that it’s lidar that works more like radar, in terms of using spread spectrum encoding to get precise distances.

Modi just says : The Indian-Chinese border has not fired a shot in 40 years. Why u worry about China. china already declares not the country to fire n bomb first.
That’s the problem with arms races: No final victory is possible, unlike an actual war.

(not!) Coincidentally, India had its first successful nuclear test in 1974, *over 40 years ago*. Poor Tibet, they should have had a nuclear program, they might still be independent and inhabited by Tibetans.

Scientists, mathematicians and engineers, making the impossible possible since we decided to settle down and farm. There are many things that are impossible but mostly it is a lack of imagination by you stick-in-the-mud types. Those starry-eyed types are the ones that make the future that I want to live in.

In the original comment, Gaucho was lamenting about yet more military spending… He was implying that a modest investment in MSR technology would (imperial trumpets blaring) save the planet. but instead we spend it on weapons (sad trombone wah wah wah wahhhh). Aw shucks. Understanding what is: the people with the power invest in weapons to protect our interests. Typically, much of this weapons research trickles down, right? Right? The military is the only entity actually pushing technology – commercial ventures are iphones and whatever other consumer junk. It’s all just part of my anti-MSR campaign. If the MSR truly had any advantages, the military would be using them, right? They are only attractive on paper if you neglect all the details. This stick in the mud is doing his part to improve critical thinking among otherwise reasonably intelligent netizens.

I have a shed full of axes to grind. There is nothing to figure out with MSR; criticality can be had – at any power level – in a bucket. That is the story – physics over. All the stories about MSR are “no new tech” and “deploy-able tomorrow”, etc. Yeah, well we could build that bubbling slop MSRE again tomorrow – that much is true. Also true: there are zero operating. Whyizdat? Pfft.
You seem to have an axe to grind. Even nuclear technologies are just tools. Why do you care if someone else is “wasting” their money on a reactor that will never work? That is their money to loose. Hey, they may have figured out something you didn’t and actually make it work.
