What is a Doppler Filter? The magnitude of the Doppler frequency of an echo signal is detected by different Doppler Filters. These Doppler filters can be implemented either as hardware by …

Pulse-Doppler signal processing is a radar and CEUS performance enhancement strategy that allows small high-speed objects to be detected in close proximity to large slow moving objects. …

Pulse Doppler filtering on groups of 8 or greater pulses with a fine grained clutter map. Aircraft are detected in ground clutter and / or rain with the Doppler filter bank & use of 2 PRFs.

May 28, 2011 · By measuring the Doppler rate, the radar is able to measure the relative velocity of all objects returning echoes to the radar system – whether planes, vehicles, or ground …

One solution to this is to use a bank of matched filters with Doppler shifted waveforms, which can be used to determine the Doppler shift of the reflected pulse. The radar system can estimate …

Moving Target Indicator (MTI) and Pulse-Doppler (PD) processing use the Doppler shift of the different signals to enhance detection of moving targets and reject clutter. Unambiguous range …

The Zero Doppler Filter may be carry out as a digital low pass filter. It detects targets with a Doppler frequency corresponding with a radial speed of less than 20 knots.

Doppler processing makes use of digital filters to cancel signals from fixed and slow targets. The proposed filter would be designed as digital filters to eliminate interference and clutter and …

This paper deals with the design of the Doppler filter bank for non-uniform pulse repetition interval (PRI) radar in the presence of signal-dependent clutter.

Jun 14, 2016 · This paper considers the design of robust filters for radar pulse-Doppler processing when the interference is a wide sense stationary random process.
