Description: Bi-dimensional Gabor filter with DC component compensation
This version of the 2D Gabor filter is basically a bi-dimensional Gaussian function centered at origin (0,0) with variance S modulated by a complex sinusoid with polar frequency (F,W) and phase P described by the following equation:
G(x,y,S,F,W,P)=k*Gaussian(x,y,S)*(Sinusoid(x,y,F,W,P)-DC(F,S,P)),
where:
Gaussian(x,y,S)=exp(-pi*S^2*(x^2+y^2))
Sinusoid(x,y,F,W,P)=exp(j*(2*pi*F*(x*cos(W)+y*sin(W))+P)))
DC(F,S,P)=exp(-pi*(F/S)^2+j*P)

Description: The CS5460A is a highly integrated power measurement
solution which combines two
Analog-to-digital Converters (ADCs), high-speed
power calculation functions, and a serial interface
on a single chip. It is designed to accurately measure
and calculate: Real (True) Energy,
Instantaneous Power, IRMS, and VRMS for single
phase 2- or 3-wire power metering applications.
The CS5460A interfaces to a low-cost shunt resistor
or transformer to measure current, and to a
resistive divider or potential transformer to measure
voltage. The CS5460A features a
bi-directional serial interface for communication
with a microcontroller and a pulse output engine for
which the average pulse frequency is proportional
to the real power.

Description: 雷达通信一体化系统，针对非波动目标以及波动目标的雷达探测性能分析。-he dual-frequency MPPSK-MODEM platform is a flexible one. When ranging accuracy request is low or platform is particularly affected by power limitations, the platform would perform both data transmission and range measurement with single frequency modes. In this paper, the ranging resolution of MPPSK pulse waveforms with the match filter and impacting filter processing method are discussed, respectively. Also, the selection of MPPSK modulation parameters for ranging is considered. In particular, requirements that allow for employing such special parameter values for range measurements with high accuracy and high range are investigated. Moreover, high repetition frequency (HRF) bi-phase code MPPSK pulse train base on m sequence are presented, the ranging accuracy of the proposed signal with the match filter processing method is deduced. In addition to theoretical considerations, the paper presents system simulations and measurement results of single-frequency MPPSK intergated systems, d
