Solid small-sized microwave electronic control scanning travelling crane radar device

Abstract

The invention discloses a solid small-sized microwave electronic control scanning travelling crane radar device, which comprises small-sized electronic control scanning array antennae, a receiving and transmitting diplexer, a receiving and transmitting amplifier, an orthogonal frequency modulation continuous wave receiving and transmitting front end, a digital signal processor and a human-computer interface, wherein a measured angle can be flexibly locked, and field-of-view width can be adjusted by the array antennae; a field-of-view barrier is irradiated by the receiving and transmitting front end through the frequency modulation continuous wave, and the frequency difference of a back wave is measured to solve the distance of the barrier; the false alarm rate and the false alarm leaking rate can be reduced at multiple conditions by the digital signal processor according to the measured barrier direction, distance, change predicated converge risks and distance of barrier; the travelling crane computer is alarmed or reported through the human-computer interface; and the distance monitoring precision can be effectively improved on the premise of not obviously improving the complexity and the cost of the system.

Description

technical field [0001] The invention relates to the technical field of automobile active protection, in particular to a solid-state miniature microwave electronically controlled scanning driving radar device for automobile forward and side collision avoidance technical problems. Background technique [0002] With the increasing popularity of the automobile market, automobiles have entered every household and become a must-have for a family. It is common to see automobile collisions, especially automobile rear-end collisions. According to data, a large number of automobile rear-end collisions are caused by The negligence of the driver, so the technology for preventing the loss caused by rear-end collisions emerges in an endless stream. In addition to the improvement of the car hardware, there are also various driving radars assembled on the car. At present, there are many microwave driving radars in the prior art. device, the Chinese patent number ZL02136542.3 with an applica...

Problems solved by technology

However, narrow-beam directional antennas for fixed lanes limit the width of the observation field of view, and cannot be used to monitor lateral targets and have a high probability of false alarms when cornering; at the same time, time-division multiplexing half-duplex mode shapes narrow pulses , Transceiver switching speed and processing system delay requirements are very high, in order to ensure good reception and identification of short-distance transceiver pulses, so the limitations in short-distance target observation are large

At the same time, multi-channel pulse groups have different frequencies, thus occupying a wide bandwidth and limiting the improvement of system capacity
