Abstract: A system and method of an adaptive transmitter for an object detection system having an adaptive transmitter that enables changing power levels to meet health and safety requirements based on proximity information. Adaptive transmitters are placed on gateway pillars of a multi-sensor gateway system using an adaptive transmitter configuration. A patron passes through the center of the gate and always stays far enough away from the transmitters such that the transmitter operates in a high field configuration and remain under appropriate health and safety levels. A patron can also move close to a pillar and enter the second proximity boundary wherein the system would automatically switch to a lower power setting to remain within the appropriate health guidelines. A two-mode power level configuration can be extended to a continuous mode configuration where the power levels are adjusted dynamically. Furthermore, power consumption can be reduced and battery lifetime prolonged.

Abstract: A system and method of threat detection using a pulsed polarimetric radar system using microwave range of frequencies in the electromagnetic spectrum. The system uses a radar principle to transmit and receive the scattered response from the target. A time pulsed upconverted frequency system is used to sample the target over a specified radio frequency (RF) bandwidth. The full 2-port scattering matrix (comprising all co and cross s-parameters) is captured using only one antenna with an OMT and delay lines, that represent the target. Several decompositions are used to describe the polarimetric signature of the target. The system uses polarimetric approaches to measure scattering properties of anomalous object concealed beneath clothing. The co-polarized and cross-polarized signals are analyzed to determine if a person is carrying an anomalous object beneath their clothing.
