Abstract
Laser radar is an optical, non-contact, polar measurement system, and this talk goes inside the range measurement. Christoph Naab sets out the instrument's spherical and Cartesian coordinate systems and its angle encoders, then takes apart the frequency modulation on which the ranging depends: chirps, the transmitted and received signals and the beat frequency between them, the absolute function of a general triangle wave, and a Fourier series expansion of it carried to first and second degree so that the resulting beat frequencies can be compared with what theory predicts.
