Radar Emitter Localization Using TDOA
This paper presents passive radar emitter localization using the Time-Difference-Of-Arrival (TDOA) technique from Unmanned Aerial Vehicles (UAVs) working in conjunction with a fixed/mobile station (such as a shipborne/land-based station) to geolocate a radar emitter to fulfill maritime and littoral area surveillance. Instead of using multiple stationary sensors, multiple TDOA measurements are o...
متن کاملData Compression for Emitter Location
Locating emitters by cross-correlating received signals to compute their time-difference-of-arrival (TDOA) and the frequency-difference-of-arrival (FDOA) requires that signal data received at one platform be transferred to the other platform. Often the data link used has insufficient bandwidth to accomplish the transfer within the time requirement, and therefore use of data compression is neede...
متن کاملAdvanced Communications Specific Emitter Identification
Radio Frequency Identi cation (RFID) tags are used to track inventory and for automatic recognition of ID cards and passports. Reproduction of the electronic equivalent of an RFID chip, commonly known as RFID cloning, is a straightforward process and can lead to serious security breaches. A cloned RFID badge can allow for unauthorized access to secured areas. Speci c Emitter Identi cation (SEI)...
متن کاملIII-nitride micro-emitter arrays
III-nitride micro-emitter array technology was developed in the authors’ laboratory around 1999. Since its inception, much progress has been made by several groups and the technology has led to the invention of several novel devices. This paper provides an overview on recent progress in single-chip ac-micro-size light emitting diodes (μLEDs) that can be plugged directly into standard high ac vo...
متن کاملA simple X-ray emitter.
A compact X-ray emission instrument is made, and the X-ray spectra are measured by changing the applied electric potential. Strong soft X-rays are observed when evacuating roughly and applying a high voltage to an insulator settled in this device. The X-ray intensity is higher as the applied voltage is increased. A light-emitting phenomenon is observed when this device emits X-rays. The present...
