In this paper, considering multiple interference regions simultaneously, an optimal antenna deployment problem for distributed Multi-Input Multi-Output (MIMO) radar is investigated. The optimal antenna deployment problem is solved by proposing an antenna deployment method based on MultiObjective Particle Swarm Optimization (MOPSO). Firstly, we construct a multi-objective optimization problem fo...

Micro-Doppler, induced by micro-motion of targets, is an important characteristic of target recognition once extracted via parameter estimation methods. However, micro-Doppler is usually too significant to result in ambiguity in the terahertz band because of its relatively high carrier frequency. Thus, a micro-Doppler ambiguity resolution method for wideband terahertz radar using intra-pulse in...

The problem of detecting slow-moving targets using a space-time adaptive processing (STAP) radar is addressed. The determination of the optimum interference-rejection weights at each range is based on snapshots at neighbouring ranges. However, in virtually all bistatic configurations or/and when using conformal antenna arrays (CAA), snapshot statistics are range dependent, which results in poor...

The 1215–1400 MHz band is important for spectroscopy of H i at high redshift, pulsar work, and SETI. Observations at these frequencies are complicated by pulsed interference from ground-based aviation radars. In this paper, we characterize one such radar received at the Arecibo Observatory using coherently sampled data sets obtained during a recent observation. Using these data, we demonstrate ...

Radiolocation has been previously studied for CDMA networks, the effect of Multiple Access Interference has been ignored. In this paper we investigate the problem of Radiolocation in the presence of Multiple Access Interference. An extensive simulation technique was developed, which measures the error in location estimation for different network and user configurations. We include the effects o...

Forming a Synthetic Aperture Radar (SAR) image while suppressing an airborne broadband jammer can potentially destroy large regions of the image. In addition to this, multipath reflections from the ground, known as hotclutter (HC) or terrain scattered interference will add a nonstationary interference component to the image. Using multiple antennas on a SAR provides spatial degrees of freedom a...

In this paper, we consider the waveform design of a multiple-input multiple-output (MIMO) transmitter which simultaneously functions as MIMO radar and base station for downlink multiuser communications. addition to power constraint, require covariance transmit be equal given optimal radar, guarantee performance. With formulate solve signal-to-interference-plus-noise ratio (SINR) balancing probl...

An interference prediction scheme is proposed for power control in packet-switched TDMA wireless networks. The prediction scheme is based on the interacting multiple model (IMM) estimator, and it is adaptive to a wide range of nonstationary dynamic characteristics of the interference power. Compared to Leung’s scheme, it can predict the interference power more accurately and allow us to adjust ...

Interference is a key factor in radar return misdetection. Strong interference might make it difficult to detect the signal or targets. When occurs sidelobes of antenna pattern, Sidelobe Cancellation (SLC) and Blanking are two unique solutions solve this problem (SLB). Aside from approach, probability false alert likelihood detection most essential parameters radar. The chance alarm for any sys...
