TLDR

  • Interactive reference covering every core radar formula from propagation and range to STAP and MIMO, with derivations and context.

Key Takeaways

  • The range-Doppler ambiguity product R_u v_u = c²/(8f_c) is fixed by carrier frequency alone; no single PRF can maximize both simultaneously.
  • LFM chirp pulse compression decouples energy from resolution: compressed range resolution equals c/(2B) regardless of pulse duration T.
  • The radar range equation’s R⁴ dependence means doubling detection range requires 16x more transmit power or 4x more antenna gain.
  • CFAR variants (CA, GO, SO, OS-CFAR) each target a specific failure mode; CA-CFAR degrades at clutter edges, OS-CFAR handles non-Rayleigh clutter.
  • MIMO virtual aperture synthesizes N_t * N_r virtual channels, giving N_t times the angular resolution of a conventional phased array at the same physical size.
