Abstract:

The optimal cut angle is studied in passive sensor triangulation when system errors exist. Since system errors cannot be avoided in practical application, the measure errors of the sensor can be assumed as Guass distribution with non-zero average. Then the optimal angles with different measure errors of two sensors are calculated under different criteria, and the influence of the system errors and measure precision on the optimal cut angle is discussed. The obtained results can be used to reference the deployment of passive sensors and improve the location accuracy.
