NextGen 8 GHz Pulse

The NextGen Pulse Radar is a true close range pulse radar with a range resolution better than 11 cm, a range up to 25 m and a pulse width of 0.5 nanno-seconds.

The system operates with the SkyRadar FreeScopes Software which provides many scopes (A-Scopes, B-Scopes, PPI), control interfaces and filters. Customers can start small and extend the application over time, just by purchasing and downloading additional modules in our portal. The radar allows for highest flexibility in the learning process, with a very low peak pulse output power (-0.7 to 6.3 dBm).

The radar transceiver is mounted into the horn antenna and can be connected alternatively to a parabolic reflector. The antennas are hardwired on the transceiver card. The transceiver is connected to a microcomputer for Digital Signal Processing. The device can be placed on a rotary tripod.

This system has been developed for training and research in civil aviation, universities and industry. It does not include any special military feature.

Basic Configuration

The system comes in its basic configuration with NextGen 8 GHz FreeScopes Basic I, providing features like

Tx Power Control
STC,
FFT (1-dimensional),
Static Threshold
CFAR (1-dimensional)
IQ data blocks
MTI
Contrast

The users are enabled to do manipulations independently on their computers. Free floating panels of the FreeScopes Control Center allow each student to set up his own signal conversion chain, analyzing raw data, data after FFT, STC etc.

Extended Configurations

The system can be supplied in a package with several extensions of FreeScopes or it can be extended progressively:

NextGen 8 GHz FreeScopes Basic II with 3D-Scope, Heatmap CFAR (2-dimensional), RCS, FFT (2-dimensional), Windows functions, Spectrogram, etc.
NextGen FreeScopes ATC I including radar plots, radar tracks, MTI with Post Processing, MTD, MTD with Doppler Filter
NextGen FreeScopes ATC II including Kalman filter, clutter map, signal delay block, add and subtract, etc.
NextGen Artificial Intelligence I including AI Solutions for image recognition and classification
Programming Interface from FreeScopes to MATLAB, PYTHON and other numerical computing environments.

The following subjects can be trained with the system, depending on the included FreeScopes Packages:

Experiments on Pulse and Emission Power
Experiments on A-Scope, B-Scope and Plan-Position-Indicator (PPI)
Calibrating a radar using amplification, filters and settings
Experiments in a fixed position as well as through panning and rotation (rotary tripod required)
Doppler Effect
Fast Fourier Signal Transformation (FFT) and its effects.
Clutter processing e.g., through Sensitive Time Control (STC), Threshold limitation or C-FAR
Radar Cross Section (RCS) analysis allowing for an understanding of the varying detectability of objects based on material, absolute and relative size, reflection angle, distance and strength of the signal.
Allows analyzing performance and false alarm tolerances through adjustment of the sensitivity.
Adjustable decision threshold allowing for experiments on background noise.
Moving Target Indication for clutter elimination
And much more.
