What kind of black magic fuckery is this O.o
- LeifCarrotson 6y agoSynthetic aperture radar. As an EE, I consider it important to understand that nothing at any level in your technology stack from silicon to SAAS to smartphones is black magic. This is just an application of the physics of high frequency electromagnetic signals. I haven't personally done work with SAR, but I imagine it's much the same as dealing with EMI/EMC in PCB development: extend Maxwell's equations from a simple case to the general principle, simulate, test, and tune. I'd have to go back to my textbook and review to figure out the exact mechanisms and the limiting factors for resolution and power, I think I have Johnson's "High Speed Digital Design: A Handbook of Black Magic" on a shelf around here somewhere...
