Target Discrimination in Synthetic Aperture Radar Using Artificial Neural Networks Jos´e C. Principe, Senior Member, IEEE, Munchurl Kim, and John W. Fisher, III, Member, IEEE Abstract— This paper addresses target discrimination in syn-thetic aperture radar (SAR) imagery using linear and nonlinear adaptive networks.

Radar Target Identification Using Spatial Matched Filters L.M. Novak, G.J. Owirka, and C.M. Netishen MIT Lincoln Laboratory Abstract The application of spatial matched filter classifiers to the synthetic aperture radar (SAR) automatic target recognition (ATR) . The objective of radar performance prediction is to estimate and quantify the prerequisites of a radar system to sense its surroundings. Usually the factors to quantify relate to observing or identifying a target and are consequently largely affected by its scattering properties, i.e. the radar cross section (RCS).

  I would like to take this occasion of Roger McGuinn’s birthday to direct you to Roger McGuinn’s Folkden, hosted here at ibiblio.. Each entry includes the history of a folk song, the lyrics and chords, and Roger’s recording of the song. Routledge & CRC Press are imprints of Taylor & Francis.

Isar imaging using matlab. Radar - Radar - Factors affecting radar performance: The performance of a radar system can be judged by the following: (1) the maximum range at which it can see a target of a specified size, (2) the accuracy of its measurement of target location in range and angle, (3) its ability to distinguish one target from another, (4) its ability to detect the desired target echo when masked by large.

On the other hand, if the radar is set up for kilometer display increments, we would use the µSecond value (again from the reflected interval column), and this time would be called "one radar kilometer". At this point, one of the fundamental radar design considerations must be presented, expressed in mathematical terms.

Radar Target Detection: Handbook of Theory and Practice covers a set of graphical solutions to the detection problem, designated as Meyer Plots, for radar systems design. A radar system's major purpose is the detection and location of an object by means of a. The cumulative histogram is the fraction of pixels in the image with a DN less than or equal to the specified DN.

It is a monotonic function of DN, since it can only increase as each histogram value is e the histogram as defined in Eq. () has unit area, the asymptotic maximum for the cumulative histogram is one (Fig.

).In this normalized form, the cumulative histogram. Target Detection with a Near-Space Vehicle-Borne Radar. Like the detection course in other radar systems, target detection with an NSVBR is a decision problem that is realized by establishing a threshold signal level (voltage) on the basis of the current interference voltage.

Then, the detector will make a decision on the presence of a. When a target vehicle's direction of travel creates a significant angle with the position of he stationary RADAR, the relative speed will be less than the true speed.

Since the change in the signal's frequency is based on the relative speed, the RADAR speed measurement may be less than the car's true speed. When using only Mode 3/A radar beacon to identify a target, use one of the following methods: a.

Request the aircraft to activate the "IDENT" feature of the transponder and then observe the identification display. Request the aircraft to change to a specific discrete or non-discrete code, as appropriate, and then observe the change. radar will always display the vehicle closest to the radar.

Let us consider an antenna ideally located at the front of the car, laying in the (x, y) us consider a planar array antenna of K N × K M elements, where each one transmits and receives the signal.

Let us denote with x i, i = [1,K N] and y j, j = [1,K M], z = 0 the coordinates of antenna elements. The schematic view of the antenna is shown in Figure 1. Target-to-background radiation contrast a color photograph is a 2D representation of an object using color as a feature.

Based on novel theory and fundamentals presented in the authors' earlier Artech House book, Radar-Resolution and Complex-Image Analysis, this new book describes improved technology and methods for implementing target identification solutions .A theoretical background and mathematical formulation is included for each algorithm as well as comprehensive numerical examples and corresponding MATLAB® code.

The MATLAB® implementations presented in this book are sophisticated and allow users to find solutions to large-scale benchmark linear programs.Abstract: Algorithms are described which make use of polarimetric radar information in the detection and discrimination of targets in a ground clutter background.

The optimal polarimetric detector (OPD) is derived. This algorithm processes the complete polarization scattering matrix (PSM) and provides the best possible detection performance from polarimetric radar data.
