A New Incoherent Scatter Technique in the EISCAT Svalbard Radar [PDF]

Radio Science, 2002
A special incoherent scatter technique in the European Incoherent Scatter (EISCAT) Svalbard Radar (ESR) was tested in November 1999. After the 70‐MHz IF stage the standard ESR receiver was replaced by a spectrum analyzer acting as a combination of a down‐converter, an AD converter, and a quadrature detector and giving complex digital samples at a rate ...

The Prototype Incoherent Scatter Radar System of Nanchang University

IEEE Geoscience and Remote Sensing Letters, 2021
The incoherent scattering radar (ISR) is the only ground device on Earth that can detect the parameters of the ionospheric plasma because of its large detection range, high detection accuracy, and high spatial resolution. The prototype ISR system of Nanchang University has been completed now.

The UK incoherent scatter radar

Radio Science, 1974
The UK incoherent scatter system operates in two modes. The monostatic pulsed system has been in operation since 1968, and a summary of the results obtained in this mode is given. The full multistatic CW system has been operating since September 1972 and among the preliminary results are measurements of the total vector of velocity drift.

An Incoherent Scatter Radar Simulation System Based on MATLAB

IEEE Geoscience and Remote Sensing Letters, 2020
An incoherent scatter radar (ISR) simulation system based on matrix laboratory (MATLAB) platform was introduced in this letter. The simulation system adopts a modular design concept and establishes a complete working link for ISRs according to the real ISRs principle of operation.

Research on signal modulation and processing for incoherent scattering radar

2015 10th International Conference on Information, Communications and Signal Processing (ICICS), 2015
Incoherent scattering radar (ISR) provides an efficient tool for measuring ionosphere parameters, such as electron and ion temperature, electron density and ion drift of the ionospheric plasma, etc. The modulation types and signal processing of incoherent scattering radar are totally different from the common radars.

Optimal analysis of incoherent scatter radar data

Radio Science, 1992
A lag‐profile data collection mode has recently become operational at Millstone Hill. A new data analysis technique has been developed in which one or more matrices of ion‐line lagged products are analyzed simultaneously, along with any available a priori information on ionospheric and system parameters such as ionosonde and plasma‐line estimates of ...
