Abstract: A cancellation technique embodied in a system and a radar signal processing method that is employed to detect near-range targets. The present invention uses a frequency-modulation continuous-wave (FMCW) or stepped frequency waveform and is capable of detecting near-range targets that would normally be obscured by transmitter leakage and internal reflections. This cancellation technique works by transmitting one or more reference ramp signals and then subtracting the coherent average of the transmitted reference ramp signals from a group of succeeding transmitted and received ramp return -signals. The resulting group of FM ramp return signals is noncoherently integrated to achieve more stable target detection statistics. More particularly, the present technique implements the following processing steps. Generating a predetermined number of reference ramp signals. Coherently averaging target return signals corresponding to transmitted reference ramp signals to produce a reference average signal.

Abstract: A virtual private network using domain name service proxy, and a method of virtual private networking, are disclosed. The VPN using domain name service proxy includes a user computer in communicative connection with a VPN client, at least one switch within the VPN client, and a VPN gateway communicatively connected to the VPN client. The switch receives at least one domain name service inquiry directed to the first domain name server from the VPN client, and redirects the at least one domain name service inquiry away from the first domain name server to the second domain name server through the gateway. The gateway unencrypts the payload and sends the payload to the second domain name server, which returns to the gateway a resolution of the at least one domain name service inquiry.

Abstract: An information monitoring system, and a method of monitoring information, are disclosed. The information monitoring system includes a network, at least one central server, at least two site servers, and at least two telephone exchanges, wherein at least one telephone exchange is connected to each site server. The system also includes at least two site server compilers, wherein each site server compiler compiles a first plurality in a universal database format, and at least one central server compiler, wherein the at least one central server compiler compiles the universal database formats into a primary universal database.

Abstract: Low frequency radiating elements are embedded in a flared notch array. The flared notch array forms a series of parallel troughs in which absorptive loads are placed to reduce the antenna radar cross section. The low frequency radiating elements are embedded in the array transverse to the troughs at or below the level of the absorptive loads, and excite several troughs. The absorptive load material is absorptive in the operating band of the flared notch array, but appears as a relatively low loss dielectric at the lower frequencies of operation of the low frequency radiating elements. The low frequency radiating elements can perform Identify Friend or Foe functions in the UHF and L-band regions of the spectrum, while the flared notch array operates at X-band.
