Deceptive jamming is a standard technique for an intelligent target to spoof a radar system. Specifically, the target firstly intercepts the transmitted signal of the radar system, and then broadcasts it with a controlled delay. As the broadcasted (deceptive) pulse is usually stronger than the direct reflection extracted by the receiver, an additional false detection will be claimed by the radar system...
This paper studies local data fusion for sequential detection. Let a sensor network monitor a Gaussian phenomenon in Gaussian background noise, and let the observation of each sensor be a vector r. In order to reduce the communication burden, each sensor reports a linearly fused scalar x=wT r instead of the raw data r to a processing center, which executes sequential detection. The aim of this paper...
The cooperation of an active acoustic source and a large number of distributed passive sensors offers an opportunity for active sonar detection. The system works as follows: first, each sensor compares its matched filter output with a given threshold to obtain a binary local decision—“0” or “1”; then, a fusion center (FC) collects them to make a system-level inference. How effectively to combine these...
This paper studies the detection performance of two different statistical MIMO radar models: one transmits orthogonal waveforms, the other identical. As for the latter, assuming there is no violation of peak power constraints, the allocation of power among transmitters is unimportant from the viewpoint of detection. For full power transmission, the latter model may outperform the former at medium...
