Ku-band Ku-band ground interference is very small, the Ku-band frequencies, generally between 11.7-12.2GHz, less susceptible to microwave radiation interference, greatly reduces the requirements of the receiving environment; receive Ku-band antenna aperture size is small, easy to The installation is not easily found; Ku - band width, capable of delivering a wide range of business and information; Ku-band downlink forwarding device transmit power (about 100W or more), energy concentration, and convenient to receive. Impact of rainfall on Ku-band satellite broadcasting is more serious, their uplink and downlink signal rainfall attenuation is much larger than the C-band, instantaneous rain attenuation of Ku-band uplink or downlink rainstorms of more than 20dB, while the C-band rain attenuation amount is generally not more than 1dB. It is the supply management of laser pointer .Based on laser detection Smart car control system design 2.1 BTS7970 drive circuit diagram in Figure 2.2 motor drive block diagram of the control system design based laser detection Smart car. The overall design of the model car. The car overall design of the car using the four way, this way the structure is simple, easy to implement various provisions of the action, stable and reliable, and simple disassembly, etc., and sufficient to meet the requirements of the car functions. Smart car with two driven rear wheels and two-oriented front-wheel program. Body for the purchase of standard body, combined with other components of the connection between the connection is completed and the aluminum alloy plate and bolts.
Nd: YAG solid-state lasers, and more suitable for space applications. A disadvantage is that the electro-optical conversion efficiency, this shortcoming has been a part of the improvement. 4.2.2 The fast, accurate acquisition, tracking and target (APT) APT is the technology to ensure the realization of the inter-satellite, one of the key technologies of satellite and ground laser communication in space, under the conditions of the order of the divergence angle of the u rad, capture precise targeting and tracking is to establish communication links between the ultra-long-distance high-speed movement of the terminal core technology, the system is usually divided into two parts: the capture (coarse tracking) system to capture the target within the larger field of view , the capture range of up to ± 1 ° to ± 20 ° or greater. It is the management of the enterprise of laser pointer .
