Colormap and Contour Figures. Colormaps and contour figures are useful for plotting functions of two variables. In most of these functions we will use a colormap to encode one dimension of the data.

The "arange" function in pylab (which you would have to load at the top) makes a list of numbers from 0 to 0.05 in increments of 0.001. So, x and y are just two lists. The line with the mesh grid ...

You can choose linear interpolation or thin-plat smoothing spline to fit contour surface functions. You can also toggle, identify and label observations in the contour plot, control the orientation of ...

Aiming at the problem that the radar emitter recognition accuracy is low, the recognition algorithm is complex, an algorithm that recognize radar emitter using ambiguity function contour plot is ...
