Abstract
In a moving object, the bulk movement is sometimes complemented with additional intermittent periodic vibrational or rotational movement (called micro-motion) which creates side-band Doppler frequency shifts about the carrier frequency (called micro-Doppler effect). The structural components of each object generates a distinctive pattern of frequency shifts (called micro-Doppler signatures) used for the identification of the object. By extracting features from micro-Doppler signatures, the targets and objects of interest are detected and identified.

Multi-antenna radar systems are being used for an improved quality of target information. Multi-static radars offer diversified degrees of freedom and arbitrary geometrical patterns that can be exploited according to the target specifications. Today, with high resolution multi-antenna radars and the corresponding modern signal processing techniques, the extraction of micro motion features has become feasible. Thus, distributed radar micro-Doppler signature-based approach is a new method for non-cooperative target identification, recognition, and classification. This talk will introduce fundamentals of micro Doppler signatures and multi-antenna radar systems. How time frequency analysis of micro-Doppler Signatures is used to carryout target detection and identification. We will discuss the use of MIMO or distributed radars as possible solution for detection and identification micro-Doppler signatures of low RCS targets. In addition, we will discuss the current and future research on micro-Doppler based radar applications, challenges and opportunities for researchers working in the area of radar signal processing.
