Dual-station direction finding location based on disturbance detection

The application of direction finding location technology in electronic warfare is becoming more and extensive. Aiming at the problem that traditional method will greatly affect accuracy when measurement information each observation station disturbed, a dual-station algorithm based on disturbance detection proposed. uses least squares to obtain target’s position moment, then designs an improved Kalman filter with improve accuracy. simulation results show can still accurately track target which has practical value.
