| Title: | DIRECT POSITION DETERMINATION OF NARROWBAND RADIO TRANSMITTERS | ||
| Authors: | Anthony J. Weiss; Tel-Aviv University | ||
| Abstract: | The most common methods for location of communications or radar transmitters are based on measuring a specified parameter such as signal Angle-of-Arrival or Time-of-Arrival. The measured parameters are then used to estimate the transmitter location. These methods are sub-optimal since they are indirect and involve two separate estimation steps. We propose a technique that uses exactly the same data as the common methods but the estimation of location is based on Maximum-Likelihood and the location determination is direct. Although there are many stray parameters, including the attenuation coefficients and the signal waveform, the method requires only a two-dimensional search. Monte-Carlo simulations indicate that the accuracy is superior to Angle-of-Arrival, Time-of Arrival and their combination | ||
