Ultra Wideband Perimeter Surveillance Pole / User’s Manual Overview This document is a User’s Manual for the Time Domain Ultra Wideband (UWB) Perimeter Surveillance Pole (PSP400). The document is divided into the following sections. Section 1 Section 2 Section 3 Section 4 Section 5 System Introduction & Theory of Operation Pole Overview P400 Radar Broadspec Antenna FCC Compliance The user will note we have not included a Section on installation and system bringup.
Ultra Wideband Perimeter Surveillance Pole / User’s Manual 4 Figure 1 is a conceptual depiction of the USS. As suggested in the figure the USS can track and independently classify multiple people and animals using its system of radars. A server processes data from the radars and provides outputs to external users of the data. A network connects the radars to each other and the server.
Ultra Wideband Perimeter Surveillance Pole / User’s Manual The number of poles deployed at a given site depends on the length of the perimeter that requires monitoring. The poles are organized into groups of six poles referrred to as networking cells. As shown in Figure 3 the physical footprint of a networking cell is a rectangle that is 100 meters long by 20 meters wide (note the radar coverage area extends up to 20 meters beyond the cells footprint in all directions).
Ultra Wideband Perimeter Surveillance Pole / User’s Manual 6 The end user provided server should feature multicore processors and an operator terminal consisting of a keyboard and monitor. Such a server is needed to support the system’s processing and interface operations. The operator terminal is for the purpose of configuring, controlling, and maintaining the system. Figure 4 illustrates a typical server.

Ultra Wideband Perimeter Surveillance Pole / User’s Manual Each network cell is implemented as a fixed TDMA scheme that supports a 4 Hz update rate. This fixed TDMA cycle and timing information is available to each P400 and ensures only a single P400 (within each cell) is radiating at any given time. The TDMA network for each networking cell is 264ms in length and contains 8 time slots. The 264ms time period is called a superframe.
Ultra Wideband Perimeter Surveillance Pole / User’s Manual 1.2.4 Graphical User Interface (GUI) The Graphical User Interface (GUI) function provides visual output to the operator terminal and controls to allow the operator to change configuration data, start and stop the system, enable or disable certain functions, etc. If remote connectivity is available, the GUI allows remote access to the operator terminal. The visual output consists of tracks overlaid on a background image of the area.
Ultra Wideband Perimeter Surveillance Pole / User’s Manual 2. Pole Overview An assembled pole is approximately 6 inches in diameter and 10.5 feet tall (Figure 8). It is mounted on an end user provided concrete footing. The footing has four threaded studs that protrude above its top surface. The pole’s base plate has four holes. The pole is erected by aligning the four holes in the base plate with the threaded studs and securing the base plate using nuts. The nuts can be adjusted to level the pole.
Ultra Wideband Perimeter Surveillance Pole / User’s Manual 11 The Base Plate Cover protects the support electronics mounted on the pole’s base plate as shown in Figure 9 the support electronics consist of: An Ethernet switch An AC/DC converter A DC Power Terminal block The Ethernet switch connects the radars in the pole to the network Ethernet cable. The AC/DC converter converts AC power into 12V DC power which is routed through the DC distribution block to the radars.

Ultra Wideband Perimeter Surveillance Pole / User’s Manual 3. P400 Radar The radar is Time Domain’s P400 Ultra Wideband (UWB) module (Figure 13) configured to provide monostatic and bistatic radar operation. Monostatic radar operation is a single device receiving scans from its own transmitted pulses. In a bistatic mode one radar receives scans (pulses) transmitted from another radar.

Ultra Wideband Perimeter Surveillance Pole / User’s Manual To power the board, the user must supply a maximum of 5 Watts at any voltage between 5.75-30V. Indicating lights provide operating status information. The user can interface to the P400 through either USB (standard USB Micro B connector), Serial connection, or Ethernet. Power is provided via a barrel connector. In addition, the user can request the P400 to report the board temperature and can command the fan to turn on or off.
Ultra Wideband Perimeter Surveillance Pole / User’s Manual 4. Broadspec Antenna The P400 is designed to operate with the Broadspec antenna shown in Figure 16. Use with ANY other antenna invalidates the FCC certification. Per FCC 15.203, the Broadspec antenna must be professionally installed and the installer has the responsibility to insure that the Broadspec antenna is used.
Ultra Wideband Perimeter Surveillance Pole / User’s Manual 5 FCC Compliance The PSP400 has been designed to be in compliance with the FCC regulations governing UWB Surveillance Systems (Part 15.511). Time Domain as manufacturer is in charge of all marketing. Any purchasers (nongovernment) by commercial clients will be informed of their responsibility under FCC rules by receiving a copy of Section 15.
