What are Range-Doppler maps?
Range-Doppler maps are two-dimensional representations used in radar signal processing to visualize the range and Doppler characteristics of detected objects. They display intensity or power levels based on range (distance) and Doppler frequency shift. Typically, range is plotted along one axis, representing the distance of detected objects from the radar transmitter, while Doppler frequency shift is plotted along the other axis, indicating speed or movement of these objects compared to the radar. Range-Doppler maps provide a comprehensive view of radar performance, assisting in target detection, tracking and classification.
The Range-Doppler algorithm is a signal processing technique used to generate Range-Doppler maps from radar return signals. It involves several steps, including pulse compression to improve range resolution, Doppler processing to extract velocity information, and spatial filtering to improve map clarity. Various algorithms, such as Fourier transform-based techniques and paired filtering, are used to accurately calculate range and Doppler information. The resulting Range-Doppler maps help radar operators analyze and interpret target characteristics, such as range, speed and direction, in civil and military radar applications.
Range-Doppler Range in MATLAB is a tool provided by the MATLAB Signal Processing Toolbox to visualize and analyze radar signals in the Range-Doppler range. It allows users to plot and manipulate Range-Doppler maps, allowing detailed examination of radar yields and target characteristics. MATLAB provides functions and utilities for processing radar data, implementing Range-Doppler algorithms, and displaying results in graphical formats. Range-Doppler scope in MATLAB is widely used in radar research, development and operational environments for its versatility and capability in handling radar signal analysis tasks.
