Abstract:
A technique for estimating the closest point of approach (CPA) of an object includes: tracking a range rate of the object based on Doppler measurements of the object; computing a first CPA estimate based on the tracked range rate; separately tracking a position of the object based on position measurements of the object; computing a second CPA estimate based on the tracked position; and computing a fused CPA estimate based on the first and second CPA estimates.
