Fpga Based L - Band Pulse Doppler Radar

Development of Broadband Radar and Initial Observation

We have developed a broad-band radar which is the precipitation Ku-band doppler radar using the pulse compression technique (bandwidth=80MHz), and observed the rainfall. We could successfully obtain the vertical profile of the equivalent reflectivity factor Ze and doppler velocity with the high range-resolution from low altitude.

Micro-Doppler Ambiguity Resolution for Wideband Terahertz Radar Using Intra-Pulse Interference

Micro-Doppler, induced by micro-motion of targets, is an important characteristic of target recognition once extracted via parameter estimation methods. However, micro-Doppler is usually too significant to result in ambiguity in the terahertz band because of its relatively high carrier frequency. Thus, a micro-Doppler ambiguity resolution method for wideband terahertz radar using intra-pulse in...

Extending the Radar Dynamic Range using Adaptive Pulse Compression

The matched filter in the radar receiver is only adapted to the transmitted signal version and its output will be wasted due to non-matching with the received signal from the environment. The sidelobes amplitude of the matched filter output in pulse compression radars are dependent on the transmitted coded waveforms that extended as much as the length of the code on both sides of the target loc...

An On-Board Processor for a Spaceborne Doppler Precipitation Radar: Requirements and Preliminary Design

Use of Doppler velocity measurement in spaceborne precipitation radar is highly desirable, since it can allow more accurate retrieval of atmospheric latent heating, which depends on both cloud and rain microphysical processes and on dynamical processes, namely, vertical updrafts and downdrafts. However, if the rain within the antenna beam is very non-uniform, biases can result with conventional...
