Abstract: An exciter system (1, 2) able to communicate information between an exciter unit (10) and one or more remote units (12) or between multiple exciter units (10). The exciter units (10) may include wireless type exciter devices, such as optimum exciters (14), or they may include wired equivalent type exciter devices, such as direct connect exciters (16). The exciter devices (14, 16) inject or extract RF currents (24) in the metallic framework (22) of a vehicle. The remote units (12) couple electromagnetic fields (26) with the metallic framework (22) of the vehicle. The information is exchanged with the exciter devices (14, 16) by communications equipment (20) that modulates or demodulates the RF currents (24) and/or electromagnetic fields (26) with the information. As the RF currents (24) and/or electromagnetic fields (26) reach everywhere within, on and in close proximity to the vehicle the information is communicated throughout.

Abstract: An automatic minimum discernible signal level analyzer for evaluating the low signal level detecting capabilities of a pulse-type receiver and including an RF frequency source phase-locked to the radar transmitter frequency and capable of being adjusted in power output by circuitry which automatically measures the statistical noise content of the receiver video and adjusts the power output of the RF source so that the video signal meets preset values of probability of false alarm and probability of detection, the absolute RF power being then a direct measure of the minimum discernible signal sensitivity of the receiver under test.
