Radar undergoes quick development during the years 1930-the 40s to reach the requirements of the military. It is still broadly used through the armed forces, wherever several technological advances have created. Simultaneously, radar is also utilized in civilian applications particularly in controlling a...

It is beneficial to incorporate the time-frequency transform into range profiles of the radar image. By so doing `clouds' can be removed and structure resonance frequencies identified. 展开 关键词: Doppler frequency radar images Fourier transform time-frequency transforms ...
applications and automatically compensating to ensure the accuracy of measurement. We can expect higher frequencies such as 60 and 80 GHz to be used by non-contacting radar, as well as having double frequency in the same radar device. We will probably see more innovative probe and antenna ...
Designing circuits operating at RF frequencies means impedances are more than just a function of component capacitance, and the impact of parasitic capacitance and inductance generally increases with frequency. Further from the PA, possibly closer to the power supply or in...
2 Large bandwidth: High information rate, easy to use narrow pulse or broadband frequency modulation signal to obtain detail structural features of the target; wide expanded ability, reduce multipath, clutter, and enhance anti-interference ability; radar of adjacent frequencies Or millimeter wave identi...
A random choice of the transmitted frequencies suppresses the range ambiguity, improves covert detection, and reduces the signal interference between adjacent sensors. As a result of the random modulation, however, a noise component is added to the range/Doppler sidelobes. In this paper, ...
(QPE). The recent progress in dual-pol radar research and applications in China is summarized in four aspects. Firstly, the characteristics of several representative dual-pol radars are reviewed. Various approaches have been developed for radar data quality control, including calibration, attenuation ...
Specify the environment and target. This example uses wideband propagation channels to propagate waveforms with different carrier frequencies. target = phased.RadarTarget('MeanRCS',100,'OperatingFrequency',fc); target_pos = [8000;1000;1000]; ...
