what does it mean to store cross products in SAR product data file?

I'm reading the UAVSAR data format
For definition of two types of file we have:

MLC files (.mlc): calibrated multi-looked cross products, floating point format, three files8 bytes per pixel, three files 4 bytes per pixel, little endian.

Ground projected files (.grd): calibrated complex cross products projected to the ground in simple geographic coordinates (latitude, longitude). There is a fixed number of looks for each pixel. Floating point, little endian, 8 or 4 bytes per pixel.

I know that the schematic form of SLC file is like this:

where I and Q are successively the real and imaginary part of the complex signal for each pixel after sampling and analog to digital conversion but if I take cross product as explained here, how can I imagine MLC or GRD format schematically?
I mean which components in the SLC file are multiplied by each other to form the cross product of each pixel?
What does cross product of the pixel mean in a physical sense?
