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 paper we describe software models of CA-CFAR, OS-CFAR and the TM-CFAR detectors in the receiver of the software defined radar. A comparative analysis of these CFAR detector models in terms of detection of radar targets in conditions of real clutter is performed. Software models of CFAR detector are implemented in MATLAB.

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...

It is planned that the TIGER N.Z. radar will be a digital evolution of the current analog system, where the phasing matrix for both transmitter and receiver arrays, and the receiver architecture will be implemented in Field Programmable Gate Array (FPGA) technology. Producing a fully digital system in FPGA technology allows a different solution to the current analog approach. An added challenge...

Synthetic Aperture Radar (SAR) imaging algorithm for the moving targets with some motion irregularities are investigated. For accurate SAR imaging of the moving targets, position and the velocity of the object according to the radar platform must be known accurately. To calculate the instantaneous range and velocity of the object, local radar platform with one transmitter-two receiver (OT-TR) i...

Expanding radar applications in the area of measuring vibration movements could improve the effectiveness of modern defence systems. The purpose of the vibration measurement is to enrich the information of a targets signature, thus improving the process of target identification and classification. The basic mathematical models of a single receiver radar and a radar that operates as an interfero...

This report investigates the suitability of a number of broadcast band transmitters of opportunity for a passive radar. Specifically, this report reviews the design of active radar waveforms, measures emissions for representative transmitters of opportunity, and assesses the suitability of these signals for various types of radar observation. This report shows that it is indeed possible to cons...

We consider the problem of reachback communication in sensor networks. In this problem, a large number of sensors are deployed on a field, to measure the state of some physical process that unfolds over the field and to then cooperatively send this information back to a distant receiver for further processing. We formulate the problem as a multipleinput, single-output (MISO) system, and develop...
