There are two main problems in bearing-only tracking: system's nonlinearity and inscrutability of the range of target.
被动式目标跟踪主要存在两个问题：系统非线性和距离不可观测性。
Tracking target by using anti-helicopter mine (AHM) is actually the bearing-only measurement because precision of range detected by passive acoustic measurement cant satisfy the need of tracking.
目前被动声探测距离精度还不能满足跟踪的需要，因此，反直升机智能雷对目标的跟踪问题归结为仅有角测量的跟踪问题。
The conventional bearing only measurement tracking filter is unable to track a maneuvering target.
传统的仅有角测量跟踪器不能跟踪机动目标。
