One of the major impacts of the Earth’s ionosphere on spaceborne radar signals is the rotation of the polarization vector, also called the Faraday rotation (FR) effect. The FR effect increases with decreasing frequency. It is reported [1] that estimated maximum FR values under peak ionospheric total electron content (TEC) conditions range from 2.5 degrees (C-band) to more than 320 degrees (P-ba...

This paper describes a combination of a Weaver mixer and an N-path filter for a superheterodyne receiver with a reconfigurable frequency plan. It uses an N-path topology driven with two different frequencies, effectively realizing a frequency shift together with band-pass filtering. To reduce transfers via harmonics other than the fundamental, a harmonic rejection scheme is used. A 28 nm FDSOI ...

This paper proposes a novel multiscale estimator for the integrated volatility of an Itô process with harmonizable increments, in the presence of market microstructure noise. The multiscale structure is modelled frequency-by-frequency and the concept of the multiscale ratio is introduced to quantify the bias in the quadratic variation due to the microstructure noise process. The multiscale rati...

Tracking the movement of people in indoor environments is useful for a variety of applications including elderly care, study of shopper behavior in shopping centers, security etc. There have been several previous efforts at solving this problem but with limited success. Our approach uses inexpensive pressure sensors, placed in a specific manner, that allows us to identify multiple people. Given...

The Dual-frequency Precipitation Radar (DPR) installed on the Global Precipitation Measurement (GPM) core satellite is being developed by JAXA and NICT. This paper describes the mission objectives, the precipitation measurement method and techniques, and the construction of the DPR. Keywords-GPM; DPR; precpitation measurement

Abstract The aim of a transfer path analysis (TPA) is to view the transmission vibrations in mechanical system from point excitation over interface points reference point. For that matter, Frequency Response Functions (FRF) or Transmissibility Matrix determined and examined conjunction with forces at path. This paper will cover application an operational TPA for wind turbine model. In doing so ...

Presented in this paper is an empirical model for long-term rain attenuation prediction and statistical prediction of site diversity gain on a slant path. Rain attenuation prediction on a slant path is derived using data collected from tropical regions, and the formula proposed is based on Gaussian distribution. The proposed rain attenuation model shows a considerable reduction in prediction er...

Network analysis is often focused on characterizing the dependencies between network relations and node-level attributes. Potential relationships are typically explored by modeling the network as a function of the nodal attributes or by modeling the attributes as a function of the network. These methods require specification of the exact nature of the association between the network and attribu...
