The full range of our Digitizing Receivers line builds on the strong tradition of Teledyne Defence & Space’s (TDS) broad range of Digital Frequency Discriminators (DFDs) and Sequential Detector Log Video Amplifiers (SDLVAs).
Teledyne Defence’s Instantaneous Frequency Measurement (IFM) module, also known as a Digital Frequency Discriminator (DFD), offer high speed frequency measurement across multi-octave frequency range.
Frequency Activity Detection
Many advanced EW receivers, particularly those associated with ECM jamming systems, do not require the high resolution frequency information associated with a DFD or IFM based receiver. This is typically the case where a single pulse present within a broad frequency band is required to be detected and instantaneously down-converted to an IF band.
Teledyne Defence & Space (TDS) has over 30 years of experience in the design and manufacture of Detector Log Video Amplifiers (DLVAs). These devices are used extensively in applications requiring an output voltage related to the power of a received RF signal. These units are used primarily in direction finding, channelised receivers, and phase array radar.
