Disclaimer: I still play 5th edition, so anything I say here might be just a little out of date. 6th edition has changed certain things, and I don't know off the top of my head if the costs have changed.
Let's take your description of "powerful radar".
This sounds like a few different things, operating together. First, you've got the ability to detect electrical devices. That's easy. Under the "Enhanced Senses" section, there's a power called Detect. When you buy Detect, you define what it is that your sense helps you locate. So you buy Detect: Electrical Devices, and there you go.
At its base level, Detect will allow you to sense electrical devices that are right on top of you. You take a half phase to use your power, and if you're basically within touching range, you can sense if there are any electrical devices there. Not very effective, but hell you only spent 3 points. So you could basically sit there, concentrate, and you'd be able to tell if there are any electronics within arm's reach. To upgrade this power, you need to spend more points. For 2 more points, you can turn your Detect (which requires a half-phase to use) into a Sense. Instead of having to actively look for electronics, you will automatically sense if they are there. You no longer have to spend a half phase, now you just sense if electronics are present. So now you've spent 5 points.
So far, so good. But maybe you want to sense electronics that are farther away than arm's reach. Now you buy Range on your Detect. That's 5 more points. Now it works more like eyesight (not exactly like it, we'll get to that later). You can now sense electronics at a distance.
Now there are some extra things to consider. I'm not sure exactly how your powers are supposed to work (I don't watch anime, and have no idea what character you are trying to duplicate), but it kinda sounds like one of the following may apply (you don't have to buy all of these, each can be purchased separately):
360 degree sense -- for 5 more points, your sense radiates out from you in all directions (like hearing) instead of in a limited field (like vision)
Targeting -- for 10 more points, you can sense electronics with enough precision to shoot at them at a distance, even if your other senses aren't working
Discriminatory -- for 5 more points, you can discriminate between types of electronics. You can tell the difference between a cell phone and a TV
Analyze -- (must have Discriminatory first) for 5 more points, you can determine super levels of detail about the different electronics
N-Ray -- for another 10 points, you can detect electronics through walls
To me, it sounds like your power would probably have all of those. Detect: Electronics (3 pts), Sense (2 pts), Range (5 pts), 360 degrees (5 pts), Targeting (10 pts), Discriminatory and Analyze (10 pts), N-Ray (10 pts). That's 45 points, which is a lot for an enhanced sense. But it allows you to sense all electronic devices within normal human visual range (to boost the range, you buy levels of Telescopic Sense), in all directions, you can distinguish what they are and how they work, you can see them through walls, and you know where they are with enough precision that you can shoot robots blindfolded. Now there are some ways to save points, but I need a better idea of exactly what the power looks like before I can apply those.
That's the first part of the power that you've described. Getting a blueprint layout of nearby buildings is going to require sensing things other than electronics. After all, you don't detect concrete, or chairs, or bathrooms. You only detect electronics. Your character would probably be able to see all the electrical wiring in a building, but you wouldn't know where ordinary doors were. I would suggest adding the power Spatial Awareness (22 points) to allow you to sense physical objects that are nearby. Or just the regular Radar power (15 points), which operates like normal radar.
Finally, you've got analyzing the components of the air? I don't understand how that is related to a radar sense, or sensing electronics, but I haven't seen the anime so I don't know. This will probably have to be an entirely separate power. So we're back to buying another Detect. Let's go with Detect: Air, with the Ranged, Discriminatory, and Analyze additions. Now this takes a half phase action for you to take a look at the air and figure out if there are any weird gases or anything in it. It'll tell you the precise makeup of whatever air you're currently sensing. So that's 18 more points.
So total, you're spending 45 points for the Detect: Electronics, another 15 for basic Radar sense, and 18 for Detect: Air. That's 78 points, which is a huuuuge amount to spend on Enhanced Senses. Again, there are some pretty easy ways to bring those costs down. You can get some of those add-ons for free, depending on how you set it up. But I don't have enough info to do that at the moment. And it may be that whatever cool thing the guy did in the anime, might be simulated far more inexpensively. The "brute force" method of Hero character creation often leads to really expensive character builds, because somebody over-engineers the thing. The effect that you are imagining might be done a whole lot cheaper. We just need more info.
