Abstract : Sequential estimation (Kalman filtering) is applied to the problem of locating a stationary radiation source, given passive, noisy measurements of bearing from a moving aircraft to the source. Several candidate estimation algorithms are investigated, with evaluation of each by Monte Carlo simulation. The most effective of these is one in which linear estimation is done about a nominal bearing trajectory whose parameters are continually updated by nonlinear prediction equations as source location estimates are produced.
