Re: Japanese Defence Minister: Helicopter & DDG "locked on" by Chinese Frigates' Ra
I think some of us need to cool our jets a little. Nobody, not even the most hardcore China haters want a war between China and Japan, least of all the Japanese. This isn't 1931 any more, and the Japanese will get no benefit and receive a hell of a beating if they attacked China, and even the US would be doubtful to take their side if they fired the first shot.
The Japanese have no real 'hard evidence', this isn't like America loosing a drone in someone else's back yard which could be paraded in front of TV cameras and leave no doubt. Whatever evidence the Japanese can provide can be discredited with very little difficulty, because whatever evidence they could provide could have been fabricated just as easily. It's pretty much the same with all the China hacking claims. It always amuses me how western hackers operating out of their mom's garage can never be traced, yet Chinese hackers who are supposed to be military trained, and who can break into all sorts of secure networks no one else can penetrate can be traced to specific computers in China.
Now, on the one hand, it could be the Japanese are thinking, hey look, the west is taking this equally ridiculous hacker story bait, line and tackle, so they will swallow this radar lock story just as easily. Plus, it would be all but impossible for the Chinese to disprove such a accusation.
On the other, it is also possible that the Chinese government are thinking, radar locks are almost impossible to prove with hard evidence and it will just be a case of 'he says, she says', so what can they really prove?
But I think both extremes unsatisfactory because it always has to be one government or the other lying to the world on purpose. Even if we rule out the morality issue, I just don't think it's smart policy to go on record with a big fat lie no matter how improbably it would be to get caught out.
Government hate either telling the truth or a blatant lie, but they love the grey area in between. As such, I think the specific wording of the Chinese press release is worth examining in detail, since the Chinese at least, are very conscious of choosing their words with great care and deliberations, which goes some way to explaining why they take so long to issue any sort of official statement.
I think the Chinese focus on mentioning fire control radar by name might be more nuanced than being specific.
But first, I think we need to be clear what a radar lock on means. This might seem obvious to most of us here, but a ship or planes radar warning receiver goes off when it detects radar waves operating in bands typically used in fire control radars (x-band) illuminating the receiver over a certain power threshold (btw, LPI radars work by keeping their emissions individually below this power threshold, but scan lots of times using many slightly different frequencies and then piecing all the weak returns together to forms big return, but I digress).
However, not all x-band radars are fire control radars. It is worth noting that many marine navigational radars and radar range fingers also operate on the x-band, but to name a few things. I remember a story from a reliable source, where the RAF were scratching their heads when the self defence suit on Typhoons stationed at a certain RAF base would suddenly activate and give the pilot firing solutions to a spot on a nearby motorway. There was nothing wrong with any of the ECM suits, and after much investigating, it was discovered that a couple of patrol cops were using their radar speed guns to clock the speeds of passing Typhoons when they were on traffic watch, and that was similar enough to fire control radars that had they been doing this in a war zone, they would have eaten an ALARM missile for their troubles.
I think the general public has a somewhat distorted idea of what a radar lock-on means, probably from watching too much Top Gun. There is no real-time synchronised beeping and flashing of little red lights. RWR are set to go off when radars operating within a wide range of frequencies hit the RWR with a high enough amount of energy. The RWR by its very nature need to err on the side of caution, as it needs to cover all sorts of threats from many countries and systems, and a false positive is better than missing a lock.
Frankly, it would not be hard to imagine how Chinese range finding or even navigational radars could have set off the Japanese RWRs, especially when you consider just how close they were operating to Chinese ships at the time of these 'lock-ons', because the closer you are to the emitter, the stronger the signal, especially in the case of high frequency radars that loose their energy very quickly, like x-band radars.
What more, fire control radar wartime operating frequencies are some of the most closely guarded secrets of any military, because if an enemy found that out, they can potentially develop tailored countermeasures to make your weapons useless. And I personally do not believe the Japanese or Americans have a record of the wartime frequencies of modern Chinese fire control radars. If anything, it would have been a big intelligence coup if the Japanese did manage to record such frequencies from this incident. In which case I hardly doubt the Japanese would be complaining and making such a big deal out of it. Looking at it from the other side, I find it hard to believe that a Chinese commander would order the use of his fire control radars because of the valuable intel he would be giving away.
If anything, I think the Japanese have made a blunder and gifted China some valuable data because obviously their RWR went off, and depending on how modern their self defence suits are and their settings, they might have also actively broadcasted jamming signals automatically. These jamming signals are also very useful for CECM, and given the high tensions and how much of a deal the Japanese are trying to make of this, I doubted their pilots and ship captain were using training mode if and when they did start jamming.
I do wonder if all the fuss the Japanese are making is supposed to try and compensate themselves for, and justifying they potentially giving away very valuable signals and frequency characteristics to the Chinese so cheaply. After all, if the Chinese did use their fire control radars, its not so much of a screw up since the signals and frequencies the Japanese recorded would be useful to them if things did turn hot. And/or they are thinking we might as well try and make some political hay out of this and make the most of a bad situation.
So, to sum up, I have little doubt that the Japanese RWR went off, and that the pilots and Japanese captain thought at the time that they had been targeted. However, I also believe the Chinese government when they specifically denied that fire control radars were used on the Japanese ship and helo. I think another type of radar was the cause of the Japanese thinking they had been locked on, maybe making them think that was deliberate, where range finding or navigational radars were being used in an atypical fashion designed to give the impression off a lock on without actually using the ships fire control radars to avoid giving away sensitive signals.
Not in the event of a real military conflict, but paving the way for one. Remember how both 9.18.31 and 7.7.37 got started
