Abstract: A radiation type oscillator including a radiation type oscillator substrate including a microwave transistor for generating negative resistance by short-duration operation and a resonant cavity structure; a high-frequency pulse signal of an oscillation frequency/frequency bandwidth determined by negative resistance produced by the short-duration operation of the microwave transistor and the resonant cavity structure is generated as a transmitted RF signal and simultaneously radiated into space. The radiation type oscillator performs oscillating operation when a received RF signal that is a reflected wave of the transmitted RF signal from an object of detection enters the radiation type oscillator, an IF signal is acquired from an IF signal output terminal owing to homodyne mixing by the radiation type oscillator itself, and this is analyzed and processed to detect the object of detection.

Abstract: An apparatus includes an extendable wand, and a sensor head coupled to the wand. The sensor head includes a continuous wave metal detector (CWMD) and a radar. When the wand is collapsed, the wand and the sensor head collapse to fill a volume that is smaller than a volume filled by the sensor head and the wand when the wand is extended. Frequency-domain data from a sensor configured to sense a region is accessed, the frequency-domain data is transformed to generate a time-domain representation of the region, a first model is determined based on the accessed frequency-domain data, a second model is determined based on the generated time-domain representation, the second model being associated with a particular region within the sensed region, and a background model that represents a background of the region is determined based on the first model and the second model.

Abstract: An iterative method for modifying an initial time signal to form a created signal having a prescribed envelope, and frequency notches at prescribed frequency values, wherein the created signal closely resembles the initial time signal, the envelope of the created time signal is the prescribed envelope, and the Fourier magnitude of the created time signal at the prescribed frequency values is nearly zero. The created time signal may be a real-valued signal as well as a complex-valued time signal which closely resembles an arbitrary initial time signal, including initial time signals which are standard transmit signals for radar systems, and which have Fourier transform magnitudes with notches and stop-bands at prescribed frequency values. These notches and stop bands are created by enforcing nulls of prescribed order at the prescribed frequency values within the modified time signal.

Abstract: A small unmanned aerial system (sUAS) is used for aerial and on the ground surveillance while an operator of the sUAS, or other personnel, remain at a safe distance. The sUAS system can perform an autonomous landing and can be operated at an extended, e.g., greater than 100 meters, standoff from the detection apparatus and potential harm. The sUAS may be implemented as an easy-to-operate, small vertical take-off and landing (VTOL) aircraft with a set of optical, thermal, and chemical detection modules for performing aerial surveillance and ground surveillance after landing.

The transmitter module is used to transmit a first ultra-wideband signal from a detecting position to the object.

Abstract: The burst oscillation device 20 includes the data generation part 21, the operation part 11, the signal selecting part 40 and the burst generation part 50. The generation part 21 outputs the encoded data encoded based on data for communication. At the signal selecting part 40, the pulse release timing of predetermined repetition period is randomly delayed by the PPM and further delayed randomly by the minimal time by means of the PSK modulation, thereby realizing the decreasing of the peak value of the average power spectral density.
