Least-squares algorithm for determining emitter position from passive radar bearings

Determination of emitter position from passive radar bearings is transformed into a linear least squares problem. The solution of normal equations enables fast and reliable spatial localisation of electromagnetic emitter. The algorithm was tested with data simulated as randomly perturbed bearings from a system of two or three radar stations providing azimuth and elevation or only azimuth of an emitter. Results of computational tests are given.
