To avoid the disadvantage of the traditional over-the-horizon (OTH) radar, which uses only the measurements of ionospheric parameters obtained from an ionosonde to estimate the target parameters, this paper proposes a new multiple-input multiple-output skywave OTH radar, which estimates the ionospheric and target parameters jointly by exploiting the data received by both the ionosonde and the radar...
This paper mainly focus on the transmit and receive sensors joint selection problem of distributed MIMO radar in target tracking scienario. Beacause of the limited resources of radars, a subset of radars need to be selected in MIMO radar network at every intance while making the performance to its best. For that purpose, posterior cramer-rao lower bound (PRCLB) is introduced as the optimization criterion...
Spread-Doppler clutter (SDC) caused by multi-mode propagation seriously affects the over-the-horizon radar (OTHR) detection performance for slow ships. To solve this problem, we propose to suppress multi-mode SDC using spatial information in the multiple-input multiple-output over-the-horizon (MIMO-OTH) radar system. Traditional processing algorithms need priori information of the target direction,...
The moving target detection based on compressed sending (CS) multiple-input multiple output (MIMO) radar with widely separated antennas is studied. The centralized processing is considered. The traditional centralized MIMO radar requires an exhaustive search on every possible two dimensional target velocity, resulting in huge computational complexity. In this paper, we adopt the CS technique to drastically...
Optimum antenna placement is considered for MIMO radar performing velocity estimation. A general optimization strategy for velocity estimation using MIMO radar is derived based on the Cramer-Rao bound analysis. Optimal antenna placement is investigated.We show that when orthogonal signals are adopted for transmission, symmetrically placing the transmit antennas as well as the receive antennas achieves...
The concept of multiple-input multiple-output (MIMO) radar is recently proposed inspired by recent advances in MIMO communications. A recently proposed statistical MIMO radar configuration is considered here, in which the transmit array antennas are widely spaced to enable spatial diversity with respect to the targets, while the receiver is an uniform linear array with the elements spaced half a wavelength...
