The detection of concealed targets beneath a person’s clothing from standoff distance is an important task for protection and the security of a person in a crowded place like shopping malls, airports and playground stadium, etc. The detection capability o... see more

Passive millimeter wave (PMMW) imaging systems have attracted an increasing interestover the past years due to their superior poor-weather performance compared with visible andIR systems. In passive imaging, the spatial information acquired is strictly ba... see more

Measurements of rotational lines emitted by middle atmospheric trace gases have been carried out from the Alpinestation of Testa Grigia (45.9°N, 7.7°E, elev. 3500 m) by means of a Ground-Based Millimeter-wave Spectrometer(GBMS). Observations of species su... see more

Millimeter Wave (mmWave) Massive Multiple Input Multiple Output (MIMO) has been a promising candidate for the current and next generation of cellular networks. The hybrid analogue/digital precoding will be a crucial ingredient in the mmWave cellular syste... see more

The paper investigates the theory of operation of a passive millimeter-wave seeker sensor using a fast electronic sequential-lobing technique and the experimental validation obtained through laboratory trials. The paper analyzes in detail the theoretical ... see more

The paper describes the design, simulation, and realisation of a slotted waveguide based horizontally polarized omni-directional antenna at millimeter wave frequency. This design has been optimised for minimum ripple in omni pattern and wide elevation cov... see more

Simulation and experimental results at 35 GHz, for a single target of unit reflectivity, a concrete pillar and a gun shaped object placed in the central region  of 2-D scene , have been presented using circularly co-located transmit and receive co-ar... see more
