The Influence of the spatial arrangement of the receivers of Electronic Warfare on the accuracy of the location by TDOA

This paper presented a preliminary study on the influence of geometries of receivers on the accuracy of the location by Time Difference of Arrival (TDOA). For analysis was considered a two-dimensional environment (xOy) in an channel fading by multipath. The location algorithm was based on the method...

For analysis was considered a two-dimensional environment (xOy) in an channel fading by multipath. The location algorithm was based on the method of Chan and were tested the geometries in a line, curve, inverted curve and circular to identify space variables that are related to the root mean square error (RMSE) of the location.The results demonstrated the influence of the intersection angle between hyperboles. For circular and curve geometries was observed an inverse relationship between the angle of intersection and the RMSE, with greater precision for angles near 90°. Other spatial variables such as the distance and shape, also influence the results accuracy. The line geometry did not provide valid results by the method of Chan. The conclusions have been  structured to identify rules to optimize the placement of receivers in order to increase the accuracy of the results. O presente trabalho realiza o estudo preliminar sobre a influência da disposição espacial dos receptores sobre a precisão da localização eletrônica por Time Difference of Arrival (TDOA). A análise foi realizada considerando um ambiente bidimensional (xOy) sobre a influência de um canal com desvanecimento por multipercurso. O algoritmo de localização foi baseado no método de Chan e foram testadas as geometrias em linha, em cunha, em cunha invertida e circular, a fim de identificar variáveis que se relacionam com a raiz do erro quadrático médio (RMSE) da localização. Os resultados demonstram a influência do ângulo de interseção entre hipérboles sobre a precisão dos resultados. Para as geometrias em  cunha e circular parece existir uma relação inversa entre o ângulo de interseção e o RMSE da localização, apresentando maior precisão para os ângulos próximos a 90º. Outras variáveis espaciais, tais como a distância e a forma do arranjo, também influenciam a precisão. O arranjo em linha não apresentou resultados válidos pelo método de Chan, sendo descartado desse estudo. As conclusões foram estruturadas de forma a identificar premissas para otimizar o posicionamento dos receptores com o intuito de aumentar a precisão dos resultados.
