Popis: The hypothesis of a natural sophisticated RADAR navigation system guiding hornets flight and detecting obstacles and preys is derived from the investigation of the complex spike elements arrays on their cuticle skin shown by electronic microscope pictures. The occurrence of three different lengths and disposition of the spike elements lead from analogy with antenna and radio theory and practice to the hypothesis of transmitting and receiving phased arrays antennas operating at different frequencies in the sub-millimetric wavelength bands. The natural photo and piezo electric generation of energy in the hornets found previously explain how can be obtained the Radio Frequency (RF) energy required for the operation of the natural RADAR system. In this paper are presented a comparison with the bats well known sophisticated sonar tracking system and a description of the possible operation and main parameters of the complex three mode detection and tracking hornets natural RADAR. Following a discussion of the possible experimental and theoretical investigations still required for reaching final conclusions on a precise model of a sophisticated hornets tracking three mode RADAR system. It is possible that the results of the proposed investigations will provide tools to improve real tracking system performances especially in the yet not operative submillimeter wavelength ranges.
