Table 2: Speed presets

The K-MD2 controls the Radar Front End (RFE) and

receives demodulated signals. It processes the sig-

nals to detect objects, sending the results to the main

system using a serial or ethernet interface. There is

a powerful GUI available to visualize the signals and

target lists and change the settings.

Speed and Range Settings

There are several predefined range and speed set-

tings selectable. However there is also the possibility

to change the range and speed settings out of the

presets.

Even though the K-MD2 is able to drive a band-

width of 1 GHz in most countries the K-Band

is limited to a bandwidth of 250 MHz.
