| Abstract: |
| A fast method for orthogonal phase coded signals of MIMO（Multi-input Multi-outp
ut） radar is proposed to solve the problem that traditional optimization algorithms are complicated and time wasting because of combinatorial optimization. Based on chaotic map sig
nals which get perfect property of correlation and randomness, binary phase code
s are obtained by choosing and binarying sequences generated from Henon and
Logistic map series. Then they are modulated to orthogonal phase coded signals.
Simulation and analysis prove that it is fast to introduce Henon and Logistic m
ap sequences into the design of appropriate orthogonal binary phase coded signal
s. |
