Multispectral scanner is designed for acquisition of the multispectral spatially matched quantitative information on both reflectance and emittance of the on-ground objects. Mechanical scanning is used. Six spectral channels are operable in the range of 0.4 -12.5 tm. All the channels are provided with the removable sets including four optical filters for each channel. Switching or change of the filters can be performed by the remote control unit. The channels are designed to match spectral ranges that are similar to those which can be found in space sensors for TM-84, ETM, SPOT, NOAA. The digitized field of view is 51.2°. The instantaneous field of view for each channel is 5 minutes. The precision of optical matching for all the channels is no worse than 1/3 of pixel. The selectable scan rates are 1 8, 36, and 72 scans per second. In the channels of the range 0.43 -0.9 jim the multispectral scanner ensures the values of signal/noise ratios 80 -200; within the range of 1 .5 -2.5 xm signal/noise ratios is no less than 100, and within the range of 8 -I2.5 jim no less than 25.

The brief theoretical analysis shows the resonant microwave compressor provides the output pulse power higher than the traveling wave power in the storage cavity. The experimental study was made with the model of the S-band microwave compressor. The power of pulses generated by the device reached the value three times as much as the value of the traveling wave power in the storage cavity at the maximum amplification 23 dB, peak power 400 MW, and pulse width 4-5 ns.
