Specialized datasets designed for mining scenarios are the essential foundation for the development, operation, and research of intelligent mines. Currently, the available datasets focus primarily on open-pit mines, with a lack of specialized datasets for underground mines. This gap severely hinders…
We consider the problem of millimeter-wave (MMW) imaging for concealed objects using a transceiver antenna array. In practical implementations, larger array element spacing leads to aliasing in the spectrum of the received echo signals. In this paper, we propose a new imaging method by de-aliasing.…
We consider the problem of unknown emitter geolocation using the time difference of arrival (TDOA) of the path rays through the ionosphere by multiple coordinated distant receivers. We formulate the geolocation in the sense of maximum likelihood with the exact ray expressions for the quasi-parabolic…
We consider the degree distribution design of the low-density parity-check (LDPC) code ensembles for symmetric Gaussian multiple-access channels (GMAC). To characterize the probability density function (PDF) of the message passing in the process of joint decoding, we propose a new scheme to construc…
We consider the problem of geolocating two unknown co-channel emitters by a cluster of formation-flying satellites using both time difference of arrival (TDOA) and frequency difference of arrival (FDOA) measurements. As the association between the TDOA/FDOA measurements obtained by each pair of sate…
