In order to simultaneously improve system performance and resource utilization of distributed multiple-input multiple-output (MIMO) radar systems, a joint resource allocation method is proposed to address the velocity estimation problem for multiple targets tracking in this paper. The paper focuses to improve the tracking performance for key targets using the remaining resources when the general targets...
Conventional radar generally uses fixed transmit waveform, which is difficult to obtain optimal target detection performance in the presence of interference. To solve this problem, a joint optimization algorithm of waveform and receiving filter for MIMO radar is proposed. Firstly, the maximization of output signal to interference plus noise ratio is used as objective function. The joint optimization...
This paper considers the waveform design problem for MIMO radar in order to improve the detection performance. We assume that target echoes are embedded in signal-dependent clutter and colored noise. Considering that transmit waveform design directly based on detection probability is not feasible, therefore, we employ an information-theoretic criteria, namely, J-Divergence as the metric for waveform...
This paper proposes a joint scheme of sensor subset selection, optimal power and bandwidth allocation for range-only target tracking in multiple-input multiple-output radar sensor networks. First, The Bayesian Cramer-Rao Bound (BCRB) is first derived. Then, the resource allocation problem is aimed to minimize BCRB with the resource constraints. The relationship between the optimal solutions of the...
The paper proposes a robust weighted intersection algorithm for target localization using AOA measurement (RWIAOA), RWIAOA algorithm mitigates the impact of singular bearing line intersection on AOA positioning algorithm based on weighted intersection. The algorithm proposed in this paper constructs corresponding bearing line and acquires the intersections of all bearing lines according to the AOA...
Whereas the existing TOA/AOA positioning algorithm based on wireless sensor network fails to consider position error of anchor node(AN) so as to affect the positioning accuracy, this paper proposes a hybrid TOA/AOA positioning algorithm based on GDOP-weighted fusion (G--TOA/AOA). The paper deduces Geometric Dilution of Precision (GDOP) of TOA/AOA positioning method based on single node (S-TOA/AOA)...
In allusion to ray tracing problems in the localization field, a position orientating path reverse ray tracing algorithm based on cluster analysis is proposed in this paper. Firstly, a two-dimensional propagation environment model with building surface as the quasi-mirror is established in order to simulate the actual propagation environment; secondly, according to the estimated values of TOA and...
