Sonobuoys provide both a deployable acoustical signal source and reception of underwater signals of interest. These received signals are transmitted to any monitoring unit(s) that then process the signal for analysis, classification of any target, and recording on magnetic tape media for replay and post-event analysis. Both the initial detection of submarines and the localization of detected targets is usually done with passive sonobuoys, if possible, to deny for as long as possible the submarine becoming aware that an adversary aircraft is present.   Occam's  Razor offers a full range of solutions from design to data analysis.

Countermeasures include all those means of exploiting an adversary's activity to determine his intentions or reduce his effectiveness. Countermeasures may be applied against weapons operating over the entire spectrum from acoustic to gamma wave frequencies. Since the most prevalent use of this spectrum for weapons/sensor's/communications, etc. is in the radio frequency (RF) (i.e. several kilohertz to tens of gigahertz) region, most countermeasures and counter-countermeasures also operate in that region. 

GPS is a constellation of satellites that orbit approximately 11,000 miles above the Earth and transmit radio wave signals to receivers across the planet. By determining the time that it takes for a GPS satellite signal to reach your receiver, you can calculate your distance to the satellite and figure out your exact location on the Earth. 

 RF hardware design is an extremely complex and time-consuming process, Occam's Razors' design tools reduce your design risk and time-to-market by making the overall RF-to-digital design practice simpler, concise, and more robust.

Aviation radio communication depends solely on RF communication utilizing select frequencies and bands.   Occam's Razor's expertise ranges anywhere from radio communication to instrumented landing systems to inertial measurement systems in both commercial and military applications.  

 The RADAR system generally consists of a transmitter which produces an electromagnetic signal which is radiated into space by an antenna. When this signal strikes any object, it gets reflected or reradiated in many directions. This reflected or echo signal is received by the radar antenna which delivers it to the receiver, where it is processed to determine the geographical statistics of the object. The range is determined by the calculating the time taken by the signal to travel from the RADAR to the target and back. The target’s location is measured in angle, from the direction of maximum amplitude echo signal, the antenna points to. 

The terrestrial system uses both analog and digital modulation types. In analog systems, data information signals are frequency multiplexed(FDM) first and later modulated (FM) and upconverted for the transmission using RF antenna. In digital systems, data information signals are time-multiplexed(TDM) to form a baseband signal.

UWB is currently quite a hot topic in industry and academia.  UWB technology brings the convenience and  mobility  of  wireless communications to high  speed  interconnects  in  devices  throughout  the  digital home and office.  Designed for short range, wireless personal area networks (WPANs), UWB is the leading technology for freeing  people from  wires,  enabling  wireless  connection  of multiple  devices  for  transmission  of  video,  audio  and  other high  bandwidth  data.    UWB  short-range  radio  technology complements  other  longer-range  radio  technologies  such  as WiFi, WiMAX, and cellular wide area communications.  It is used to  relay data  from a  host  device to other devices in  the immediate area (up to 10 m or 30 feet).

 Redesign of obsolete electronic circuits is a valuable tool in electronic system life-cycle management. Additionally, it’s the best alternative to discarding the system when replacement parts are no longer commercially available. Depending on the system you want to redesign and the number of units required each year, it’s easily possible to achieve zero-cost development.
