In this thesis, we study the artifacts that occur when a scene being imaged by radar contains moving targets. The physics of interaction between radar waves and moving targets were studied to develop a model using MATLAB for the received signal which does not make use of the start-stop approximation. The effects of target motion in the image formation process were studied for different radar configurations, including multistatic radars and Synthetic Aperture Radar. The key limitation of this...

Target recognition and identification in battlefields has been a crucial determinant to the ultimate success or failure of modern military campaigns. Since World War II, the Identification of Friend or Foe (IFF) systems installed in radar systems have served as the primary cooperative target identification techniques based on the \"question and answer\" interrogation loop of unidentified aircraft. However, the IFF system has a number of limitations that pose significant challenges in...

The Wirelessly Distributed Digital Phased Array (WDDPA) is an ongoing research program at the Naval Postgraduate School (NPS) which has numerous possible applications in radar and communication systems. The WDDPA incorporates many array elements randomly or nonuniformly in the environment or on a platform. Array elements are synchronized and controlled over a wireless channel. Compared to conventional phased array systems, its advantages are adaptability, survivability and flexibility. Phase...

The concept of a wirelessly networked opportunistic digital phased array radar brings about the added advantages of stealth, enhanced survivability, and maximum maneuverablity. The array elements are spread over a wide range of locations on the ship's hull and superstructure, and the Local Oscillator (LO) and data/control signals are wirelessly transmitted to and from a central computer processor, which also performs as the digital beamformer. As part of the ongoing research effort, this thesis...

The radars and other systems at the Arecibo Observatory were designed and built, originally, for incoherent-scatter and radio-astronomy research. More recently, important additions have been made for planetary radar and artificial RF heating of the ionosphere. Although designed and built for a different application, these systems have shown to be very powerful tools for tropospheric, stratospheric and mesospheric research. The Observatory at present has two main radars: one at 430 and the other...

We investigate the ISAR imaging model using two different approaches the Fourier and the wavelet transform. Starting from the weak-scatter far-field model we explain why this approximation it's a Fourier Transform. We investigate the scattering mechanisms from different surfaces. We also analyze and derived the expressions of the scatter from sphere. We briefly discuss the radon transform and why it's not a good approach to our problem. We investigate the results using this time-frequency...

Topic: Radar
Weather radars permit meteorological quantities such as rainfall rate and wind velocity to be determined. These quantities are calculated from estimates of reflectivity, mean radial velocity and velocity spread. These estimates are derived from modified RF signal parameter measurements. RF scattering and propagation effects are the mechanisms which modify these parameters. Scattering is probabilistic in nature and therefore during measurement estimates of true conditions are formed. Errors in...

The Sondrestrom radar is located on the western side of Greenland near the U.S. air base and Danish community at Sondre Stromfjord. The radar was previously located at Chatanika, Alaska where its primary role was incoherent-scatter studies of the auroral ionosphere. Stratosphere/troposphere studies have occupied a very small portion of the radar observing schedule. The high operating frequency (1290 MHz) implies that the radar may only be used for turbulence-scatter studies in the troposphere...

This report investigates the possibility that meteor-nose echoes are a causative mechanism for noise currently being observed on the FPS-95 radar. A description of the noise is given as documented by on-site observers. Meteor- nose echoes are postulated as being partly responsible for the observed noise. Recent Madre Measurements have permitted a definition of the spectral character of the meteor-nose echo both in the near and far ranges. Spectral examples of each are given. The spectral...

Spectral data of 4-8 GHz radar backscatter were gathered during the 1972 growing season at look angles between 0 and 70 deg and for all four possible polarization linear combinations. The data covers four crop types (corn, milo, alfalfa, and soybeans) and a wide range of soil moisture content. To insure statistical representation of the results, measurements were conducted over 128 fields corresponding to a total of about 40,000 data points. The use of spectral response signatures to separate...
