摘要：
The PMHT algorithm is sufficiently mature to be applicable to mono-static active sonar in [1] and other researchers have investigated PMHT for multi-sensor systems. An important modification of PMHT to utilize echo amplitude information in addition to range and bearing measurements was developed in [2]. In multi-static active systems different source/receiver combinations will observe the same target at different aspect angles and different signal to noise ratios. Any multi-static tracking algorithm attempting to use amplitude information must model the effects of target aspect on the amplitudes of the observed echoes. This paper presents a scheme to use an aspect dependent model of target strength to adapt the parameters in the distribution for target echo amplitude. Results on simulated data demonstrating the improvement that can be achieved with the new method are also presented.
