It has been shown that the detection performance can be improved by exploiting the covariance matrix of the channel vector in the distributed MIMO radar. In this paper, we firstly introduce a system model in which the target is modeled as the sum of a finite number of independent scatterers without limitation on transmitter-receiver configurations. Using this system model, we make a detailed an...

The performance and capabilities of a bistatic spaceborne synthetic aperture radar (SAR) are analyzed, where the transmitter and receiver are in different orbits. Such a configuration may be optimized for a broad range of applications like frequent monitoring, wide swath imaging, single-pass crosstrack interferometry, along-track interferometry, resolution enhancement or radar tomography.

In this article, we review and compare different methods for the localization of an illuminator opportunity passive radar systems employing cooperative targets. For assessment comparison, use numerical simulations real-world measurements. To achieve reliable operation under conditions, a correct robust association bistatic target observations with ground truth information is necessary. We intro...

Radar and satellite global positioning system-platform transmitter terminal (GPSPTT) transmitters provide complementary information on the movements and behaviors of individual birds. The GPS-PTT tag provides a snapshot of altitude and location of a specific individual of an identified species at predefined intervals. The history of the individual is known because each transmitter has a unique ...

The accuracy of radar-based rain rates is limited by the calibration of radar reflectivity (ZH), which must be measured within 1 dB for rainfall estimates to have an accuracy of 15%. Several approaches to radar calibration have been undertaken which are summarized in Atlas (2002). The receive component of the radar can be calibrated using a transmitter with a known signal strength. Transmit and...

Radar exploration of the Solar System changed dramatically during and beyond the period of theMagellan mission to Venus. These changes included an expansion of the community familiar with microwave data, and the forging of a strong connection with polarimetric scattering models developed through terrestrial field measurements and airborne radar studies. During the period, advances in computing ...

High-precision radiometric calibration and synchronization compensation must be provided for distributed radar system due to separate transmitters and receivers. This paper proposes a transponder-aided joint radiometric calibration, motion compensation and synchronization for distributed radar remote sensing. As the transponder signal can be separated from the normal radar returns, it is used t...

Continuing advances in radar technology are driven both by new application regimes and technological innovations. A family of applications of increasing importance is detection of a mobile target intruding into a protected area, and one type of radar system architecture potentially well suited to this type of application entails a network of cooperating radars. In this paper, we study optimal r...
