Observability characteristics of angle-only measurement under proportional navigation
Min-Jea Tahk, Hyeok Ryu, Eun-Jung Song · 2002
Conditions for target observability with angle-only measurements are derived for several target models: stationary target, constant-velocity target, and constant acceleration target. The effects of proportional navigation on target observability are then analyzed. The analysis results show that target observability is dependent on the choice of target model and guidance gain and can be significantly degraded for certain guidance gains.
