Put the Power of UWB to Work for You

Time Domain's PulsON® 400 (P400) OEM modules offer users the ability to integrate high performance ranging / tracking, radar, and sensor communications into new or existing products. The P400 modules were designed to provide robust performance in the environments where other technologies struggle (high clutter and high multipath areas, both indoors and out) and with the flexibility to address a wide variety of applications for commercial, industrial, government and military clients.

Time Domain has developed the P400 based upon Ultra Wideband (UWB) technology. Time Domain's UWB uses the coherent transmission of sequences of short duration, low duty cycle, low energy RF pulses. The P400 is powered by our 5th generation UWB chipset, which enables the P400 to provide the superior ranging and sensing capabilities at the small size and low cost that you need to be successful.

How does Time Domain's UWB work?

• Short duration pulses: Time Domain's UWB is based on the coherent transmission and reception of very short duration (thus wide bandwidth) RF waveforms.
• Waveform is optimized for precision measurements: Because the transmitted waveform is short, with a physical length of approximately 6 inches, it is ideal for determining precise ranges and radar resolution in buildings or outdoors.
• Pulses are coded and modulated: All transmissions are pseudo-randomly coded and modulated by individually varying the phase of transmitted pulses and the pulse repetition rate.
• Coherent processing: Any type of transmitted information (ranging, data or radar) is spread over many transmitted pulses in a packet format.
• Custom silicon: All of the key UWB RF functions have been reduced to a pair of custom chips.

Key Benefits

• Precision range measurements indoors and outdoors: Because Time Domain is using the ideal RF waveform for in-building operation, an unprecedented level of performance is achieved, both indoors and out.
• Exceptional radar clutter rejection: Because each transmitted waveform is very short in duration and the system timing is so accurate, the radar provides excellent clutter rejection with virtually no blind region. Time Domain offers the most RF bandwidth (2 GHz) at the lowest possible center frequency (4.2 GHz).
• Flexible update rates for varying distances: Sending and receiving packets of coherent pulses allows signals to be coherently integrated. As a consequence, the user can dynamically trade update rate for increased operating range.
• Waveform scan available to the developer: Time Domain's P400s provide not only range measurements and radar detections but also supply the associated raw data (waveform scans). Providing this scan data allows the system integrator to develop and refine signal processing that is optimized for a given application. For example, this enables the low level fusion of ranging with radar or advanced algorithms in support of mono-, bi-, and multi-static radars.
• Noise-like transmissions: Because the signals are pseudo-randomly encoded and the signal energy is spread over 2 GHz, all transmissions are noise-like making them very unlikely to cause interference as well as very difficult to detect or intercept.
• Fused operation: Time Domain's architecture allows a single packet to be used for ranging, communications or radar applications. This capability means that a single board can be used for all three applications. Additionally, any packet can be simultaneously used for all of the three functions.
• Custom silicon enables low cost modules: Having custom UWB silicon means that Time Domain can provide the customer with a physically small, highly integratable, low cost, low power OEM module.
