MrIF / MrAIS
IF /AIS Receiver Mezzanines For MrDig
MrIF and MrAIS are the IF/analog receiver portions of the Modular Integrated Receiver/Digitizer.
MrIF Mezzanine.
KEY FEATURES
- MrIF Dual IF ESM Receiver:
- Two Channels of any of:
- 100MHz BW @160MHz or
- 600MHz BW @1GHz
- Two Channels of any of:
- MrAIS AIS Modem:
- Dual Band AIS Receiver
- Single Channel 100MHz or 600MHz BW IF receiver
MRIF/MRAIS OVERVIEW
These mezzanine modules combined with the MrDig baseboard are the core elements in the Copperfield 2 series of modular ESM receivers originally developed for the Naval Research Laboratory for use in RADAR surveillance applications. Capabilities were further enhanced with the inclusion of an AIS receiver module.
These systems have been fielded on multiple platforms over the past several years, including Predator, Globalhawk, Firescout, and HarborWing, along with other ship and land based installations.
Mezzanine Architecture
Each MIRDer Mezzanine Card contains two receiver functions, one on each side of the card. There are 3 receiver functions currently available:
- 160 MHz cf IF Receiver with 100MHz BW
- 1GHz cf IF Receiver with 600MHz BW
- Dual Band AIS Receiver
Any combination of two of the above is easily accomplished - contact us for more details. Additional Mezzanine module functions are under development which can be paired with each other or with any of the existing functions above:
- DF ESM Modules
- 1-2GHz BW ESM RF Receivers
- Other specialized processing Modules
