摘要
In this paper, we implement a previously developed sensor management framework within the domain of multistatic radar resource management. The methodology is based on controlling the Posterior Cramer-Rao Lower Bound (PCRLB) which provides a bound on the performance of any unbiased target state estimator. In the second part of the paper, the additional complication of the Doppler Blind Zone, inside which the target cannot be detected, is considered. In the case of missed detections. the PCRLB has been shown to be overly optimistic, so we use a performance measure which more accurately accounts for missed detections. However, existing measures fail to accommodate constraints arising from the blind zone, so we modify the measure to incorporate this extra information. The modified measure is shown to give a more accurate estimate of tracking performance, facilitating efficient resource management.
