The C.H. radiolocation transmitters
Journal of the Institution of Electrical Engineers - Part IIIA: Radiolocation, 1946A general description is given of the development work leading up to the final design of the C.H.-type Radiolocation Transmitters for the Air Ministry. Early modulation schemes are mentioned and reasons given for changes in circuits to meet operational requirements.

Radiolocation Experiments in an Urban Environment
IEEE Transactions on Electromagnetic Compatibility, 1970Many new urban applications of radiolocation technology in both cooperative and noncooperative forms are anticipated in law enforcement and urban planning fields. Until recently, virtually no data were available regarding passive radiolocation of urban targets by conventional techniques such as direction finding.

Raydist systems for radiolocation and tracking
Electrical Engineering, 1953Several radio systems have been developed for locating a ship's position on the earth's surface and for tracking it. The measurement of phase, as is done in the Raydist systems, offers accuracies which exceed those of other methods.

Radionavigation and radiolocation
1999There are no frequency allocations for the radiodetermination service (RDS) itself but there are many for its specialised subdivisions. Many of the stations of this family of services are categorised with the radionavigation service (RNS) which is further subdivided between the maritime and the aeronautical radionavigation services (MRNS and ARNS ...

2008 Conference on Human System Interactions, 2008
In the article the results of simulation and investigations of the influence of the shift between signals ldquoIrdquo and ldquoQrdquo on location proprieties of the chirp signal have been discussed. Weight Hamming function and rectangular function have been used for the investigations.

Current problems of meteorological radiolocation
Journal of Communications Technology and Electronics, 2016The specific features of meteorological radiolocation and its state of the art are discussed. The characteristics of weather radars manufactured by all companies leading in this field are compared. The problems facing weather radars and possible methods of their solution are determined.

Dual antenna array for radiolocation of RCIED trigger
2014 Twentieth National Conference on Communications (NCC), 2014We describe a dual-antenna design for use in radiolocation of remote controlled improvised explosive device (IED) triggers in the 136–174 MHz frequency band. Each antenna array consists of 8 dipole-fed corner reflector antennas mounted in a circular array, radiating mainly in azimuth and elevation planes respectively.
