Microwave energy at specific frequencies and sufficiently-high power can cook you. While water has some rotational modes all throughout the X- and K-bands of the electromagnetic spectrum, radar guns are restricted by FCC regulations on power levels. Modern common/standard LIDAR-based radar guns operate with ~30ns pulses at <50mW power (905 nm wavelength, or 331 THz). By comparison, a microwave oven, which operates at about 2.45 GHz, typically outputs >600W of microwave power (with leakage of <5mW). So, to cook you with a radar gun, it'd take 12000 times longer than a microwave oven takes to heat water, assuming you don't radiate off the energy you absorb faster (depends on how well our bodies retain heat).I don't think I'd want one aimed at me close up because microwave energy can cook you.
