Un radar multistatique est un ensemble radar qui comporte au moins trois composants — par exemple, un récepteur et deux émetteurs, ou deux récepteurs et un émetteur, ou encore plusieurs émetteurs et plusieurs récepteurs pour sonder un espace commun.
La résolution d'un radar est sa capacité à distinguer deux cibles très proches l'une de l'autre, en azimut ou en distance. Cross Range Resolution | What is Cross Range Resolution of Radar. OUTLINE 1. Ces cartes d'accumulations donnent cependant un bon aperçu.

radar cross-section σ is a specific parameter of a reflective object that depends on many factors, and which has units of m². Ils peuvent présenter des différences avec la réalité mesurée par les pluviomètres officiels de la rubrique "stations - relevés". It has limited dimension which is perpendicular to radar antenna axis. Les cartes ont une résolution d'environ 1.5 km / pixel. A perfectly conducting sphere of projected cross sectional area 1 m 2 (i.e.

Detection and Measurement of Radar Signals: A Tutorial 7th Annual ISART Frank H. Sanders NTIA Institute for Telecommunication Sciences 1 March 2005 . The calculation of the radar cross-section is only possible for simple objects.
It also mentions equation of cross range resolution. This does not equal geometric area.

Ground-penetrating radar uses a variety of technologies to generate the radar signal: these are impulse, stepped frequency, frequency-modulated continuous-wave , and noise. The size of a target's image on radar is measured by the radar cross section or RCS, often represented by the symbol σ and expressed in square meters. a diameter of 1.13 m) will have an RCS of 1 m 2. This is ability of radar to differentiate multiple objects or targets present at the same range. Radar Frequencies and Waveforms 12th Annual International Symposium on Advanced Radio Technologies Michael Davis Georgia Tech Research Institute Sensors and Electromagnetic Applications Laboratory mike.davis@gtri.gatech.edu Based on material created by Byron M. Keel, Ph.D., GTRI . Note that for radar wavelengths much less than the di Les radars de contrôle d'armes, qui demandent une grande précision, doivent être capables de distinguer des cibles espacées de quelques mètres. This page mentions what is Cross Range Resolution of Radar. Radar Cross-Section.

Systems on the market in 2009 also use Digital signal processing (DSP) to process the data during survey work rather than off-line. * Cumuls: Les cumuls sont des estimations et sont établis uniquement à partir de l'imagerie radar.
