Inductively Coupled Plasma Atomic Emission Spectroscopy: Instrumentation

Inductively Coupled Plasma Atomic Emission Spectroscopy: Instrumentation

Inductively coupled plasma (ICP) is the common plasma source used in atomic emission spectroscopy (AES), a technique that detects and analyzes various elements in a sample. This method is often called inductively coupled plasma atomic emission spectroscopy (ICP-AES).
There are three main types of inductively coupled plasma atomic emission spectroscopy (ICP-AES) instruments: sequential, simultaneous multichannel, and Fourier transform instruments, with the latter being less commonly used.

Electronic Distance Measuring Instruments

Electronic Distance Measuring Instruments

Electronic Distance Measuring Instruments (EDMs) are essential tools in modern surveying, offering precise distance measurements by emitting electromagnetic signals and calculating the time required for these signals to travel to a target and return. Two primary types of signals are used in EDMs — light waves and microwaves — each suited to specific environmental and distance requirements. Light-wave-based EDMs utilize either infrared or laser light, providing high accuracy over short distances...

Area of Science:

Radar Signal Processing
Target Detection and Tracking

Background:

Stepped-frequency radar offers high range resolution but faces challenges at low signal-to-noise ratios.
Dense false alarms and range-Doppler coupling complicate detection and tracking of dim, spread targets.

Purpose of the Study:

To develop a novel methodology for joint detection and tracking of dim range-spread targets in challenging radar environments.
To address the limitations of low signal-to-noise ratios and range-Doppler coupling in stepped-frequency radar systems.

Main Methods:

A Bernoulli extended target filter is employed for joint detection and tracking.
Coherent processing results are initially thresholded low, feeding coupled detections and false alarms to the filter.
State and measurement models are developed to incorporate range-Doppler coupling, range spread, and false alarms.

Main Results:

The proposed filter effectively detects dim range-spread targets.
Simulations demonstrate good detection performance under low signal-to-noise conditions.
The method simultaneously decouples the range-Doppler coupling problem.

Conclusions:

The Bernoulli extended target filter provides a robust solution for detecting and tracking dim, range-spread targets in stepped-frequency radar.
This approach mitigates issues caused by low signal-to-noise ratios, false alarms, and range-Doppler coupling.
The methodology enables effective target detection while resolving range-Doppler coupling.
