## FreeScopes Basic II - Teaching Material

SkyRadar's FreeScopes platform offers a range of distinctive advantages and unique characteristics that make it an ideal choice for educational institutions and training programs focused on radar technology and signal processing.

### Various Algorithms for Moving Targets Applied on FMCW Raw Data (Video)

The following video shows the algorithms Moving Target Indication (MTI) , MTI with post processing, Moving Target Detection (MTD) as well as MTD with Doppler filter, applied on raw data of a 24 GHz FMCW.

### 2-Dimensional Constant false alarm rate CFAR Explained Using FreeScopes (Video)

The following video explains in detail the 2 Dimensional CFAR.

### NextGen 8 GHz: Catching Moving Targets with CFAR, MTD and a Heatmap (Video)

This video show several blocks in the digital signal processing chain that allow to enhance the visibility and tracking of moving targets. We show CFAR, Moving Targete Detection with Doppler Filtering, a Heatmap and the I and Q signals.

### Spectrogram in FreeScopes - What is it Good for in Radar Technology? (Video)

The Spectrogram looks at the received power from the targets. It represents the first one-dimensional Fourier transform and is given in a logarithmic scale. The received power spectrum allows to detect moving targets.

### Heatmap of Range and Doppler Made Visible with Fast Fourier Transform (FFT) (Video)

The following video visualizes the Doppler frequencies of a person approaching and moving away from the radar source. We apply Fast Fourier Transform.

This article features a video on an FFT plot. It has been implemented in real-time, just by connecting and calibrating the blocks in the block-diagram. The video shows well how the FFT amplitude moves to the right, when the person approaches and to the left when the person moves away from the source.

### SkyRadar's FMCW Training Radar and FreeScopes 7 - A Perfect Match

With FreeScopes 7, SkyRadar's 24 GHz FMCW training radar can be applied as simply as the NextGen Pulse radars. The students can concurrently and independently apply the Fast Fourier Transform in their browsers and switch between frequency and time domain, just as needed.
