AbstractNot Available The objective of this proposal is to demonstrate the feasibility of separating cruise missile class targets when there are multiple targets observed by the acoustic sensor. Several programs (e.g., steelrattler, FASDR) have addressed the use of small, remotely deployed acoustic sensors for collecting early warning and rough track on cruise missiles. Typically, the quality of track expected is not precise enough for use as fire control data, but rather is useful to cue fire control sensors. Acoustic sensors in this role maximize the time available to engage targets and provide very early warning of impending attack. Field experimentation has indicated that using acoustic sensor data to develop tracks of single targets is feasible and practical [Ref: Steadman, R., Air Deliverable Acoustic Sensor (ADAS), Multi-Node Data Fusion for Tracking Fast Aerial Targets , Textron Systems Division Briefing, October 1996]. The problem that has not been adequately addressed is how to develop tracks of multiple targets (cruise missiles) from acoustic data. The proposed work will demonstrate that by implementing frequency domain signal processing techniques to time slices of the data, the variation in doppler characteristics from tow or several targets can be used to separate the signatures of multiple targets.
