This paper addresses the multi-target tracking problem through the use of dynamic programming based track-before-detect (DP-TBD). The usual way of implementing DP-TBD in a multi-target scenario is to adopt a multi-target state, which is the concatenation of individual target states. But this method involves the solution of a high-dimensional joint maximization which is usually computationally prohibitive...
Track initialization and adapting to time-varying number of targets are challenges for particle filter (PF) based tracking methods, because of the difficulty of monitoring changes in the entire state space with a finite number of particles. Conversely, if the state space only has limited supports (i.e. after thresholding) or state space is well localized (i.e. target prior information is known), PFs...
The particle filter (PF) based multi-target tracking (MTT) methods suffer from the curse of dimensionality. Existing strategies to combat this assume posterior independence between target states, in order to then sample targets independently, or perform joint sampling of closely spaced targets only. When many targets are in proximity, these strategies either perform poorly or are too computationally...
The micro-vibration activities of the biologic, including heartbeat and respiration, can be detected to identify the life targets, which is widely used in rescue, remote medicine, etc. A new life detection algorithm will be proposed for stepped-frequency continuous wave (SFCW) radar, which mainly based on multi-periods and MTD filter technology to extract the micro-doppler frequency of biologic targets...
Random stepped-frequency radar chooses the transmitted frequencies randomly. For this reason, this kind of radar can suppress the range ambiguity, improve covert detection; and the correlation output is accompanied by random noise components, which increases the side-lobe level. This paper utilizes an adaptive pulse compression (APC) algorithm to suppress side-lobes, which is compared with weight...
As terminal of through-the wall radar, the main function of display&control system is accomplishing information transfer between the user and the radar: Configure the radar system according to the user, and return detected result in a laconic and effective way finally. Based on all above, the article introduced a new way to construct display&control system, and then relevant software structure...
