Matrix CRLB scaling due to measurements of uncertain origin
IEEE Transactions on Signal Processing
In many estimation situations, measurements are of uncertain origin. This is best exemplified by the target-tracking situation in which at each scan (of a radar, sonar, or electro-optical sensor), a number of measurements are obtained, and it is not known which, if any, of these is target originated. The source of extraneous measurements can be false alarms-especially in low-SNR situations that force the detector at the end of the signal processing chain to operate with a reduced threshold-ordoi:10.1109/78.928687 fatcat:lyqj2ivxfvfwno7remlhiu3jya
