Multichannel receiver camera operating in 8 mm wavelength

The receiver camera, which contains 32 sensors array and quasioptical lens antenna, is developed for scanning imaging system in 8 mm waveband. Radiometric sensors are designed as direct detection receivers with input low noise amplifiers. Input amplifier is realized on the basis of three monolithic amplifying ICs connected in series. The output low frequency amplifier is realized on the basis of IC. The sensors have a stretched configuration that facilitates their arrangement within array structure. All sensors are packaged in such a way that its feeds are placed in focal plane of the main antenna and directed towards antenna center. Receiver array with feeds and lens antenna are rigidly fixed relatively each other. The given camera allows to scan a surveyed scene 32 times faster comparing with a single receiver sensor. Thus, 32 channels receiver camera operating in 8 mm waveband is developed. During one scan the camera is capable to provide an image with good angular resolution. The further perfecting of the imaging systems requires to increase the number of receiver sensors and diameter of antenna to the greatest possible levels.
