At what rate does radiation exposure occur at high-c speeds? So - if I understand this correctly - their internal cross space/time section of proton exposure stays proportional to the external space/time volume they are moving through rather than the internal relativistic one which is slower relative to the outside space. |

How does holographic radar work? @MartinBeckett the continuous signal fits in with some of the reading I have been doing on ultra low power MRI's - which is exactly where I'm trying to go with this. Thanks again. |

How does holographic radar work? Ah very cool - I get it now. It turns out the original paper on ubiquitous radar was from Skolnik dtic.mil/cgi-bin/GetTRDoc?AD=ADA403877. The bit I was missing was that instead sweeping the transmitter phased array, the transmitter is omni-directional. The receiver 'beams' are swept electronically, therefore building up an 'interference' pattern (even though the receivers are not actually transmitting anything, they are sensitized to a direction). I'm guessing here that the transmitter still chirps? Or would we just handle the time domain slicing on the receiver side? |

How is an inflatable parabolic antenna created? Thanks. that's a lot clearer now - I missed the mandrel in my quick glance at it. Any thoughts on the Q3. How one would inflate a sphere with a parabola inside it? I still think the internal parabola must be a second balloon at a higher pressure internal to the sphere |
