Future high-resolution short-range automotive radar will have a higher false alarm probability than the conventional low-resolution radar has. In a high-resolution radar, the reception signal becomes sensitive to the difference between intended and unintended objects. However, automotive radars must distinguish targets from background objects that are the same order of size; it leads to an incr...

One of the core research areas of the “Laboratoire de Météorologie Physique” (LaMP) at the “Observatoire de Physique du Globe de Clermont-Ferrand” (OPGC) is the study of clouds and precipitations, and their corresponding microphysical processes, both from the modeling and the observational point of vues. In order to improve its observation capabilities of precipitations, LaMP/OPGC has entered a...

The Cloud Profiling Radar, the primary science instrument of the CloudSat Mission, is a 94-GHz nadirlooking radar that measures the power backscattered by clouds as a function of distance from the radar. Shortly after the scheduled launch in November 2004, this instrument will acquire a global time series of vertical atmospheric cloud structure at 500-m vertical resolution and 1.4-km horizontal...

Atmospheric parameters retrieved by remote sensing techniques often represent averages over considerable space or time intervals. Unresolved variability of corresponding primary physical values is a problem as soon as non-linear relations between the primary physical value and the retrieved parameter come into play, as for example the R(Z)relation between radar reflectivity Z and rain rate R. W...

One fundamental issue in designing a good radar system is it’s capability to resolve two small targets that are located at long range with very small separation between them. Pulse compression techniques are used in radar systems to avail the benefits of large range detection capability of long duration pulse and high range resolution capability of short duration pulse. In these techniques a lo...

It is a high-resolution radar imaging is interdisciplinary and has wide interests among many various areas.In it remote sensing, Synthetic Aperture Radar images are widely usually used to map the land of the terrain.in defense industry, it type of radar imaging of moving objects is an important tool for automatic target recognition. In this review paper, we provide a comprehensive review of rec...

Automotive radars for potential accident reduction and for autonomous cruse control were available in 1999, and 77 GHz long-range radars and 24 GHz short-range radars are developing [1]. 79-GHz shortrange automotive radars have a bandwidth of 4 GHz, a maximum range of 30 m, and a range resolution of 5 cm. Radar reception signals often contain unwanted echoes, called “radar clutter.” Moving targ...

Radar, and in particular imaging radar, have many and varied applications to counterterrorism. Radar is a day/night all-weather sensor, and imaging radars carried by aircraft or satellites are routinely able to achieve high-resolution images of target scenes, and to detect and classify stationary and moving targets at operational ranges. Short-range radar techniques may be used to identify smal...

High-resolution imaging of potential targets in advance of any spacecraft mission is important for reducing mission cost and risk and improving science returns. In particular, ground-based radar imaging provides highly-accurate ephemerides and shape and spin state information for objects that pass near the Earth. At higher resolution, radar images show surface features such as boulders and pote...

One of the parameters of the pulsed RADAR that contributes range capability is the average power of the transmitter. The average power can be increased by increasing the peak power or transmitted pulse width or both. The complexity in the design of transmitter components to withstand high peak power is the most challenging task. On the other hand larger transmitted pulse width affects the RADAR...
