Technical Report 12 - Horn Monopulse Antenna System for Millstone Hill Radar
نویسنده
چکیده
The 440-Mcps conical-scan tracker at the Millstone Hill radar site has been converted to an L-band 12-horn monopulse tracker utilizing a Cassegrain optics reflector system. The amplitude sensing monopulse feed illuminates a 10-foot subreflector and thence an 84-foot-diameter paraboloid with linear or either sense of circular polarization. This system conversion increased the capabilities of the radar complex in that higher antenna gain and increased tracking sensitivity are obtained. The merits of the 12-horn system have been proven with actual results substantiating the theoretical predictions. This report discusses the design considerations and final performance characteristics of the overall antenna system and its individual components. Accepted for the Air Force Stanley J.

متن کاملIonospheric plasma temperatures during 1976 – 2001 over Millstone Hill
Incoherent scatter measurements have been made since the 1960s over Millstone Hill. Zenith antenna data since 1976 and steerable antenna data since 1980 are now available through the WWW-based Madrigal database system. By analyzing this large volume of data in a systematic way, this paper provides an updated climatology of the ionospheric temperature over Millstone Hill, including diurnal varia...
متن کاملDesign and Experiment of a Conformal Monopulse Antenna for Passive Radar Applications
This paper proposed a design scheme of wide band monopulse antenna system for the passive radar seeker (PRS) of anti-radiation missile (ARM). To save the installation space of the PRS, the conical conformal log periodic antennas (LPDA) are employed to form the monopulse antenna system. The specific implementation scheme of PRS based on the conically conformal monopulse antennas was designed and...
متن کاملDirection of Arrival (doa) Determination Based on Monopulse Concepts
Monopulse is a classical radar technique [1] of precise direction finding of a source or target. The concept can be used both in radar applications as well as in modern communication techniques. The information contained in antenna sidelobes normally disturbs the determination of DOA in the case of a classical monopulse system. The suitable combination of amplitudeand phase-monopulse algorithm ...
متن کاملRandom Noise Monopulse Radar System for Covert Tracking of Targets
The University of Nebraska is currently developing a unique monopulse radar concept based on the use of random noise signal for covert tracking applications. This project is funded by the Missile Defense Agency (MDA). The advantage of this system over conventional frequency-modulated continuous wave (FMCW) or short pulse systems is its covertness resulting from the random waveforms immunity fr...
