FIELD: radio engineering. ^ SUBSTANCE: radar can be used for view forwarding of front semi-sphere (lower and upper) of light-weight maneuver airplanes and helicopters to prevent collision against other flying vehicles, high-voltage power lines, towers, pipes and etcetera. Radar is made of three parts: aerial which has first and second phased aerial sub-arrays and control computing unit. Any sub-array has N irradiators, phase commutator, ferrite circulator, first self-excited oscillator and low noise amplifier. Control computing unit has adder, receiver, microcontroller, second self-excited oscillator, and LCD indicator and alarm unit. ^ EFFECT: improved safety of flight. ^ 4 cl, 4 dwg |
