Modulation heterodyne radiometer has receiving antenna, key-modulator, heterodyne receiver to output of which connected in series selective amplifier of modulation frequency, synchronous detector, low frequency filter and register are connected, low frequency generator connected to control inputs of key-modulator and synchronous detector. Two T-like branches are included, two end absorbing loads one of which is low-ohm matched, and the other one – high-ohm controlled. |
