In order to improve adaptability and robustness over a rough terrain, we add a strong tracking filter
(STF)  on the basis of UFastSLAM.
Section 3.1 presents translation tracking filter
. In Section 3.2 we describe scale tracking filter
using the bidirectional scale estimation.
These include derivative control [1-3], tracking filter
technique, based on either low-pass or high-pass first-order RC filters [4-9], and notch filter technique that employs two second-order Wien-bridge filters with the incommensurate resonance frequencies .

The same problem is also analyzed in  where a comparison between EKF, a pseudo measurement tracking filter
, and a PF is pointed out.
A strong tracking filter
(STF) was proposed by Zhou , which makes the output residuals approximate to Gaussian white noise by selecting appropriate time varying gains online.

The tuner integrates a tracking filter
and high-linearity front-end, and it reduces power consumption by eliminating the second frequency conversion used in many other silicon tuners.
It includes a front-end LNA with internal AGC, a band-pass tracking filter
, frequency conversion, gain control, and channel filtering blocks, plus a synthesizer (providing the local oscillator function) and auxiliary circuits.
A PLL is a closed loop negative feedback mechanism used as a most efficient and economical frequency multiplier and tracking filter
In Figure 3, the 4th order component extracted from the sweep by GOT is shown in comparison to the same component extracted with a Vold-Kalman tracking filter
. (7,8) Figure 3 also superimposes the envelope of both of these signal components, which is augmented by two insets to reveal details.
Therefore, the multiple models based on best-fitting Gaussian approximation and strong tracking filter
will be introduced to GGIW-CPHD algorithm to track maneuvering group targets with unknown number in this paper.
