MRF 03 - An Introduction to Radar Principles (New Version)

Radar is round-trip timing done seriously. A transmitter fires a pulse, a receiver waits for a whisper of it to come back, and everything else in the discipline exists to squeeze range, bearing, and velocity out of that faint echo. This course opens with Maxwell, Hertz, and Hulsmeyer, then the echo principle, the block diagram of a primary radar, and the PPI display. The quantitative core follows: deriving the radar range equation, walking the loss budget, and covering PRF, duty cycle, and dwell time. A tour of frequency bands from HF to W-band explains why weather, surveillance, and fire-control radar live where they do, before pulse, CW, and FMCW architectures tie it to real systems. The final chapters open the hardware: antennas, phased arrays, and monopulse, then transmitters, pulse compression, and the vacuum devices, klystrons, TWTs, and magnetrons, that still anchor high-power radar. For engineers, technicians, and students who want the principles under the acronyms.
