L-band Pulsed Doppler Radar Development for Main Battle Tank

Fpga Based L - Band Pulse Doppler Radar

S-Band Doppler Wave Radar System

In this paper, a novel shore-based S-band microwave Doppler coherent wave radar (Microwave Ocean Remote SEnsor (MORSE)) is designed to improve wave measurements. Marine radars, which operate in the X band, have been widely used for ocean monitoring because of their low cost, small size and flexibility. However, because of the non-coherent measurements and strong absorption of X-band radio waves...

Bragg Resonance in Measured L-band Radar Clutter Doppler Spectra from Inland Water

A highly developed Bragg resonance phenomenon was observed in measurements of vertically polarized L-band radar backscatter recorded from the surface of a small inland fresh-water reservoir in central Massachusetts. These measurements were obtained with Lincoln Laboratory's LCE (L-band Clutter Experiment) radar sited on Wachusett Mt. from which the reservoir surface was visible at 4-km range an...

Evaluating the best main battle tank using fuzzy decision theory with linguistic criteria evaluation

To face the reality of practical multiple criteria problems usually possessing characters of fuzziness, and to consider group decision making with various subjective–objective backgrounds usually participating in decision-making process. In this paper, the experts’ opinions are described by linguistic terms which can be expressed in trapezoidal (or triangular) fuzzy numbers. To make the consens...

Doppler Estimation Using a Coherent Ultrawide-Band Random Noise Radar

The University of Nebraska has developed an ultrawide-band (UWB) coherent random noise radar operating over the 1–2 GHz frequency range. The system achieves phase coherence by using heterodyne correlation of the received signal with a time-delayed frequency-shifted replica of the transmit waveform. Knowledge of the phase of the received signal and its time dependence due to target motion permit...
