SDT Electronic Warfare Products and Projects
Electronic Warfare (EW) is very important part of the today’s combats. The countries which can effectively use electromagnetic spectrum and these technologies will succeed in the battlefield. EW, contains, both gathering information from the enemy electronic systems by capturing and analyzing the signals from them and preventing the effective usage of these system by emitting counter electromagnetic signals.
The EW Systems is grouped as following: 1) Electronic and Communication Intelligent (ELINT - COMINT) 2) Electronic Support Measures (ESM) 3) Electronic Counter Measures (ECM) 4 Electronic Counter Counter Measures (ECCM)
The basic units which compose these systems are Antennas, Analog and Digital Receivers, Signal Processing Units, Recorder Units, Operational Software, Mission Planning and Analyze Software. Design and development of these units in country is very critical for national security.
SDT has been developing and producing solutions on the Electronic Warfare area since its foundation. In the context of SDT’s activities, different projects are being carried out while several different products are being delivered both on RF and IR bands. In addition to developing EW mission systems, products for testing, measuring and evaluating current EW systems are presented by SDT as well.
Some sample projects and information about SDT’s activities on the EW area can be seen below:
“EW Systems” SDT develops integrated Electronic Warfare Systems covering different RF bands for various mission requirements.
“IR Guided Missile Simulator” allows developing/testing/improving of countermeasure techniques and tactics for IR guided anti-ship missiles. System can also be used on activities aiming to reduce the IR signature and Radar Cross Section (RCS) values.
Guided Missile simulations are made by using IR detector, special lenses, filters and Mission Software. By using the Analysis Software, performances of developed technique and tactics can be analyzed and improved. IR Guided Missile Simulator is integrated into a shelter environment.
SDT EW Products Family Keeps Expanding
In the scope of previously developed projects, some SDT EW products have been developed, which are essential for rapidly meeting similar system requirements:
“EW Recorder” allows real-time and lossless recording of Mission Data obtained from different interfaces such as Serial FPDP, Ethernet and Analog IF. Data is recorded on Solid State Disks configured as RAID arrays with speeds more than 3 GByte/s. Compatible with MIL-STD-461 and MIL-STD-810 standards is an option.
“Analog Wide Band Receiver” is used for down converting the RF signal which is obtained from antennas to the IF band. The superhet type receiver is capable of producing one Wide Band IF, multiple Narrow Band IF signals and video detector signal outputs at the same time. Receiver is controlled over its Ethernet interface.
“Digital Receiver (Pulse Analyzer)” is used for digitizing IF signals and producing Pulse Descriptor Words (PDW) of these signals. The system is capable of digitizing 1 channel wideband IF signal and 3 channel narrowband IF signals at the same time while producing regarding PDWs. Pulse Analyzer works synchronously with the Analog Receiver.
“Emitter Detection Software” is used to produce emitter list which contains information about detected emitters present on the environment. Emitter list contains information about; Frequency Values, Frequency Types (Constant, Agile, Hopping), Pulse Repetition Interval (PRI) Values, PRI Types (Constant, Jittered, Staggered, Dwell/Switch), Signal Amplitude Values, Pulse Width (PW) Values, First/Last Seen Time Values of Emitters and Intra-pulse Modulation characteristics. System is capable of processing pulses in dense environments.
“Signal Analysis Software” , is used for Offline Analysis of the radar data that has been recorded during missions. IF data and Pulse Descriptor Word (PDW) analysis can be carried out using SAY. In the scope of SAY, different representations of the data (Tabular, Spectrum, Histogram, Amplitude/Phase/Frequency vs. Time Graphs) can be displayed while Sorting and Filtering operations can be performed as well.
“EW Environment Simulator”, allows production of simulated data which is needed during development and testing phases of any kind of EW systems. After defining radar signals of different types and specifications, relevant Pulse Descriptor Word’s (PDW) are produced. It is possible to model atmospheric environment, reflections and multipath effects. Produced simulated data is presented in various forms such as digital, IF and RF.
