Brief Description
- General The Digital HF/VHF/UHF Monitoring Direction Finders R&S®DDF0xE cover the entire frequency range from 0.3 MHz to 3000 MHz or subranges thereof. The direction finders use digital signal processing both in filtering (FFT and filters with linear phase response) and in bearing calculation. Each direction finder consists of four functional units:
- DF antenna system
- DF converter with integrated receiver modules
- Digital signal processing unit
- Control PC and software
- Digital DF methods The acronym DDF in the type designation R&S®DDF0xE stands for digital direction finder, indicating that bearings are determined digitally, i.e. the complex antenna voltages are measured by a high-quality three-path DF receiver that acts like a vector voltmeter and are subsequently digitized. The bearings are evaluated using mathematical algorithms. Both the classic Watson-Watt direction finding method and the modern correlative interferometer method can be used. The Watson-Watt method is preferably used in the HF range in cases where only limited space is available for setting up a DF antenna (e.g. on ships). Moreover, it enables maximum scanning speed.
Features & Benefits Stationary VHF/UHF radiomonitoring For stationary and semimobile VHF/ UHF DF systems, the DF antenna system consisting of the R&S®ADD053 and R&S®ADD070 was designed. This antenna system together with the R&S®DDF 05E yields an extremely accurate and sensitive DF system. Mobile GSM direction finding With the GSM option installed, the R&S®DDF 05E is capable of taking the bearing of every mobile phone active in a channel. Depending on the number of occupied timeslots, up to eight bearings will be displayed on the GUI. Taking bearings of mobile phones places exacting demands on a direction finder, given that a single GSM signal packet has a duration of only 577 ?s. The ®DDF 05E, which requires a minimum signal duration of only 400 ?s, also provides reliable bearings for GSM mobile phones. Remote-controlled HF DF station In conjunction with the wide-aperture DF Antenna R&S®ADD011, the Direction Finder R&S®DDF 01E forms a DF system for the HF range of 300 kHz to 30 MHz that is remarkable for its high accuracy and sensitivity. Mobile HF/VHF/UHF radiomonitoring To provide mobile detection and direction finding throughout the entire frequency range, it takes compact DF equipment, broadband DF antennas and appropriate DF methods. Rohde & Schwarz offers optimized DF equipment and antennas that provide seamless coverage in the frequency range 300 kHz to 3 GHz. The complete range is covered by only three DF antennas that deliver very good results despite their small dimensions. Above 200 MHz, the mobile system offers DF accuracy and sensitivity as high as that of the stationary system.''
