Polarimetric radar systems allow the flexibility of transmitting arbitrarily polarized waveforms that match the scattering profiles of the target. Since different types of targets have varying profiles, the advantages of a polarimetric radar system can fully be exploited only when the type of target is accurately estimated. However, accurate estimation requires a significant amount of training ...

A model of the AN/FPQ-14 C-Band radar was developed using Analytical Graphics, Inc. (AGI) STK software to support studies investigating the operational performance of the system for surveillance of Space and the contribution it could make to the Space situational awareness mission. STK scenarios were developed to assess the detection performance of the radar model against a satellite target wit...

Radar Polarimetry and Polarimetric SAR Interferometry represent the current culmination in ‘Microwave Remote Sensing’ technology based on the Antennas, Propagation, Radar and Systems. The purpose and procedure of polarimetry and polarimetric interferometry are shown in Fig. 1. With polarimetric radar sensing, it is possible to carry out 1) detection of targets, 2) decomposition of scattering me...

In this paper, an analysis of a target location estimation system using the best linear unbiased estimator (BLUE) for high performance radar systems is presented. In synthetic environments, we are here concerned with three key elements of radar system modeling, which makes radar systems operates accurately in strategic situation in virtual ground. Radar Cross Section (RCS) modeling is used to d...

Combined ground penetrating radar and metal detector equipment are now available (e.g., MINEHOUND, ERA TechnologyVallon GmbH) for landmine detection. The performance of the radar detector is influenced by the electromagnetic characteristics of the soil. In this paper we present an experimental procedure that uses the same equipment for the detection and calibration by means of signal processing...

We are reporting on a new signal processing technique for the detection of fast accelerating targets that spread over multiple range bins and Doppler filters in the radar receiver. By compensating for these undesirable effects, improvements in coherent gain of more than 2 dB can be achieved, thus optimizing detection performance. The technique is demonstrated with simulated data, and implementa...

An artificial intelligence system improves radar signal processor performance by increasing target probability of detection and reducing probability of false alarm in a severe radar clutter environment. This utilizes advances in artificial intelligence and expert systems technology for the development of data analysis and information (signal) processors used in conjunction with conventional (de...

Humanitarian demining is a very urgent and important task for many countries and many techniques are proposed for its solution [1]. We have developed a bistatic GPR system using an Optical Electric Field Sensor (OEFS) as a receiver for landmine detection [2]. This system has two unique features, one is that it is a bistatic radar and the other one is to use a OEFS as a receiver. Therefore, it i...

Synthetic aperture radar (SAR) images are widely used in target recognition tasks nowadays. In this letter, we propose an automatic approach for radar shadow detection and extraction from SAR images utilizing geometric projections along with the digital elevation model (DEM) which corresponds to the given geo-referenced SAR image. First, the DEM is rotated into the radar geometry so that each r...

We introduce a full hardware implementation and demo of a sub-Nyquist radar receiver. Our system demonstrates pulse-Doppler radar transmission and reception at sub-Nyquist rates. Specifically, we sample the received radar signal at 1/20 the Nyquist rate, while still perfectly detecting the targets in the delayDoppler plane. In addition our system filters clutter interference from the sub-Nyquis...
