PERFORMANCE ANALYSIS OF RANGE AND DOPPLER INFORMATION FOR BETTER (S/N) SIGNAL TO NOISE RATIO USING PULSE DOPPLER RADAR

Fast Pulse Doppler Radar Processing Accounting for Range Bin Migration

An airborne pulse Doppler radar depends on a combination of range selectivity and velocity selectivity to detect targets in ground cluttsr. In principle clutter sensitivity can be reduced by employing higher bandwidths for greater range resolution. However at a sufficiently high bandwidth the phenomenon of range bin migration occurs which precludes the use of conventional Doppler processing. He...

Adaptive Doppler Filters Using Simultaneous Estimation of Target Acceleration and Signal to Noise Ratio

In order to obtain target velocity in radar systemswe use Doppler filters. For good target velocity estimation, itis necessary to apply adaptive length window functions. Theoptimum length is primarily influenced by the targetdynamics, expressed in its acceleration, and the signal tonoise ratio of the obtained echo. Using criterion of minimalcumulative error of estimation...

Performance comparison of pulse-pair and wavelets methods for the pulse Doppler weather radar spectrum

In the civilian aviation field, the radar detection of hazardous weather phenomena (winds) is very important. This detection will allow the avoidance of these phenomena and consequently will enhance the safety of flights. In this work, we have used the wavelets method to estimate the mean velocity of winds. The results showed that the application of this method is promising compared with the cl...
