Filter Bank for Clutter Suppression in MTD Radar

A filter bank for clutter suppression in MTD (Moving Target Detection) radar represents the simulation of a Doppler filter bank. In radar systems, MTD radar is a commonly used radar type that employs filter banks to eliminate clutter, thereby improving the quality of radar signals. The Doppler filter bank serves as a critical component in MTD radar, processing the Doppler frequencies received by the radar to enhance the system's ability to detect and track targets. Therefore, simulating the filter bank for clutter suppression in MTD radar is an essential task. This process requires designing appropriate filter banks by considering the characteristics and requirements of the radar system, ultimately improving the system's performance and reliability. From an implementation perspective, this typically involves designing multiple bandpass filters covering different Doppler frequency ranges using techniques like FFT-based filter banks or polyphase filter structures. The simulation would include parameters like filter bandwidth, center frequencies, and attenuation characteristics to match the expected clutter spectrum. Key MATLAB functions that could be used include fft for frequency domain processing, fir1 or cheby1 for filter design, and filter for implementation.
