Get this from a library. Measurement of power density from marine radar. [D W Peak; United States. Bureau of Radiological Health. Division of Electronic Products.;]. An attempt is made to estimate the range and magnitude of microwave exposure from marine radar and to determine if theoretically calculated power densities, using manufacturer's.
David K. Barton is a consultant on radar systems, recently retired from ANRO Engineering, Inc., of Hudson, Massachusetts. Sincehe has been the series editor of Artech House's highly Cited by: Radar - Radar - Factors affecting radar performance: The performance of a radar system can be judged by the following: (1) the maximum range at which it can see a target of a specified size.
Radar Principles is destined to become the standard text on radar for graduate and senior-level courses in electrical engineering departments as well as industrial courses. It is also an /5(7). The power density at a distant point from a radar with an antenna gain of G t is the power density from an isotropic antenna multiplied by the radar antenna gain.
Power density from radar, . Power Density Calculation Theoretical Equations () 2 2 10 20 log 4 cm R dBm R P G DF Theoretica l Power Density = TX TX = − π DF (Duty Factor) G (Total Transmit Gain) dBi P. CHAPTER 1 INTRODUCTION TO BASIC RADAR The Navy Electricity and Electronics Training Series (NEETS) modules, especially modRadar Principles, provide information that is.
The power P E returning to the receiving antenna is given by the radar equation, depending on the transmitted power P S, the slant range R, and the reflecting characteristics of the aim. 1 MW peak power (+90 dBm); that the transmitter antenna gain is +35 dBi; that the measurement system antenna gain is +25 dBi; that the measurement system is positioned miles ( km.
