Feature optimization of ambiguity function for radar emitter recognition

Extended ambiguity function for bistatic MIMO radar

This paper derives the extended ambiguity function for a bistatic multiple-input multiple-output (MIMO) radar system, which includes the whole radar system parameters: geometric sensor configuration, waveforms, range, range rate, target scattering and noise characteristics. Recent research indicates the potential parameter estimate performance of bistatic MIMO radars. And this ambiguity functio...

Robust Radar Emitter Recognition Based on the Three-Dimensional Distribution Feature and Transfer Learning

Due to the increasing complexity of electromagnetic signals, there exists a significant challenge for radar emitter signal recognition. To address this challenge, multi-component radar emitter recognition under a complicated noise environment is studied in this paper. A novel radar emitter recognition approach based on the three-dimensional distribution feature and transfer learning is proposed...

The Phase Retrieval Problem for the Radar Ambiguity Function and the Radar Ambiguity Function for the Phase Retrieval Problem

This talk is based on a joint paper with A. Bonami and G. Garrigós [3] in which the phase retrieval problem for the Radar Ambiguity Function (i.e. the Radar Ambiguity Problem) has been tackled. In particular it was shown that for wide classes of signals, the radar ambiguity problem has a unique solution, up to trivial transformations. In the second part of the talk, we report on ongoing work by...

On the Satisfaction of Modulus and Ambiguity Function Constraints in Radar Waveform Optimization for Detection

Chapter 4 The Radar Ambiguity Function

The radar ambiguity function represents the output of the matched filter, and it describes the interference caused by the range and/or Doppler shift of a target when compared to a reference target of equal RCS. The ambiguity function evaluated at is equal to the matched filter output that is matched perfectly to the signal reflected from the target of interest. In other words, returns from the ...
