Radar
Waveforms: Analysis & Design
Instructor: Nadav Levanon, Tel
Aviv University, Israel
Synopsis:
Basic tools for radar signal analysis - the matched filter
and the ambiguity function, are briefly discussed and demonstrated
on basic signals: LFM pulse, coherent pulse train and a coherent
train of LFM pulses. Advanced pulse compression signals and
sidelobe reduction techniques are then studied, including:
frequency modulation (Costas, NLFM), phase coding (Barker,
Frank, P3, P4, P(n,k), polyphase Barker, MPSL), inter-pulse
diversity (complementary, step-frequency), weighting and mismatch
filters. Also discussed are spectrum sidelobe reduction techniques
(derivative phase, Qudriphase transformation, Gaussian windowed
sinc) and CW waveforms. MATLAB software tools for radar signal
analysis will be demonstrated.
