Calculation method
Nonrelativistic Doppler shift (Hz)
Path factor × frequency × approach speed/c. Positive means approaching.

Assumptions & limits
Assumptions & limits
- Frequency, radial velocity, one-two-way convention. Returns Doppler frequency shift. All coefficients and observations are user supplied; results describe only the stated mathematical model. Quantities are deterministic calculations from supplied observations and assumptions; no external data is fetched. Supported limits: Finite inputs only; numeric fields bounded as labelled. Lists and JSON records are limited to 256 entries unless a stricter tool bound is stated. No automatic design approval, legal conclusion, treatment recommendation or safety certification. Carrier frequency (MHz): minimum 1e-12, maximum 1000000000000.0. Radial approach speed (m/s): minimum -1000000, maximum 1000000. Propagation convention: 1 one-way; 2 two-way: minimum 1, maximum 2.
