Microwave photonic receiver for radar applications comprising a continuous wave laser together with amplitude modulators and narrow-band optical filters and converting radar signal to low (envelope) frequencies is considered. Possible characteristics of the receiver are estimated and different modes of its operation are discussed. It is shown that homodyne as well as heterodyne methods for transformation...
Research using electronic microscope was carried out to study the structural and phase and deflected mode of material of hot-forged billets. It was revealed that the scalar density of dislocations in ferritic grains and in ferritic perlite layers of forging steel which cracked after manufacturing operations is one and a half time higher than in conditions material. Metal in this condition has higher...
