This invention proposes a passive bi-station cooperative positioning method based on one-dimensional azimuth measurement. By constructing an orthogonal space for azimuth observation, a measurement equation can be established between one-dimensional measurement information, time delay information, and the unknown source position. Furthermore, by introducing weighted least squares technology, the near-closed solution can be quickly obtained to determine the target source position. Under Gaussian noise, when the measurement error is small and the deviation is negligible relative to the variance, the mean square error of the positioning can reach the theoretical estimation accuracy. The proposed invention can overcome the target positioning performance limitations caused by the drastic reduction in the number of operational radars due to electronic warfare, and has significant engineering application value.
