Table 1 Parameter values used in the simulations
From: Novel maximum likelihood approach for passive detection and localisation of multiple emitters
Parameter | Value |
|---|---|
Number of sensors (N) | 20 |
Locations of sensors | Grid formation with separations of 50 m (see Fig. 1) |
Probability of detection of each target (P d ) | 0.8, 0.9, or 1.0 |
Average false alarms per sensor | 2.2 |
AOA measurement error standard deviation (σ θ ) | 1 o |
DDOA measurement error standard deviation \((\sqrt {2}c \sigma _{t})\) | 10 m |
Signal propagation speed, c | 343.2 m/s (i.e. the speed of sound in air) |
Number of target events | Up to 10 |
Target event locations | Uniformly sampled in the surveillance region [3 km, 7 km] × [-2 km, 2 km], but excluding events from occurring within 500 m of the sensor array (again, see Fig. 3) |
Target event times | Either the same or each sampled from a uniform [0, 100] seconds distribution |
