چکیده
At present, the research about radar clutter has been a special field, which greatly affects the development and application of radar in remote sensing. The radar clutter is very complicated, because it is a kind of random process, besides it isn’t visible to human. This paper presents an innovative and creative method to support this research. It makes use of ‘ 3S’ (RS, GPS, GIS) integrated technique to provide visual background information for radar signal processing.

Radar clutter is very complicated signal, because it is a kind of random process and invisible to human. As a result, besides instrumental parameters, environmental parameters will play a critical role in later data analyses. At present, the research about radar clutter has become a special field, which greatly affects the development and application of radar. This paper presents an innovative ...
متن کاملEffect of Curved Path Monopulse Radar Platform’s Grazing Angle on Height of Floated Targets Detection
Monopulse radarsare one of the most accurate tracking radars used to guide various platforms. Detection and tracking of surface targets with these radars are performed in order to point strike targets. Sea clutter presents challenges for detecting floated targets and in addition to affecting detection height, it can cause errors in monopulse angle finding. In this paper, the airborne monopulse ...
متن کاملRadar Measurements of Ice Sheet Thickness of Outlet Glaciers in Greenland
We have conducted airborne measurements over the Greenland ice sheet from the NASA P-3B aircraft using a 150MHz coherent radar depth sounder to obtain extensive ice sheet thickness measurements. Simultaneous measurements of ice sheet elevation were also made using a laser altimeter. In outlet glacier areas along the ice sheet margin, the ice surface is characterized by a very rough, crevassed s...
متن کاملAdaptation of Rejection Algorithms for a Radar Clutter
In this paper, the algorithms for adaptive rejection of a radar clutter are synthesized for the case of a priori unknown spectral-correlation characteristics at wobbulation of a repetition period of the radar signal. The synthesis of algorithms for the non-recursive adaptive rejection filter (ARF) of a given order is reduced to determination of the vector of weighting coefficients, which realiz...
متن کاملRadar Signal Detection in K-distributed Clutter by Pade Approximation
In this paper, two suboptimum detectors are proposed for coherent radar signal detection in K-distributed clutter. Assuming certain values for several initial moments of clutter amplitude, the characteristic function of the clutter amplitude is approximated by a limited series. Using the Pade approximation, it is then converted to a rational fraction. Thus, the pdf of the clutter amplitude is o...
