Description
Technical field
The present invention relates to a kind of ship-navigation radars.
Background technique
Marine radar is one of main application fields of radar, and ship for civil use pathfinder more becomes radar consumption market
Main force.Currently marketed mainstream marine radar product is still using a frequency pulse signal form, magnetron transmitter, rod-type day
Line.2006, Britain Kevin Hughes (KelvinHughes) company produced the civilian boat of First S frequency range solid state transmitter
Extra large radar system SharpEyeTM, 2008, the said firm was proposed the SharpEyeTM of X frequency range again.2011, Japanese JRC was public
Department is also proposed its S frequency range solid state pulse pathfinder product J MA-9172-SA.The same year, NAVICO company, Norway are proposed
The solid-state of its a new generation emits continuous wave radar product Broadband4GTM.2013, Japanese Gu Ye company was also proposed outfit
The FAR-3000 radar of S frequency range solid-state transceiver.New System is not only attributed to the fact that in a series of appearance of this civil marine radar
The promotion of related international organization, be also attributed to the fact that microwave power semiconductor, digital signal processing chip etc. technologies, the maturation of technique and
It is popular.
Marine radar working frequency is still based on S frequency range and X frequency range.Decaying of the S frequency range radiofrequency signal in misty rain is small, sea
The clutter backscattering coefficient that is averaged is low, therefore people are more likely to using S frequency range radar in harsh weather and high sea situation；
X band antenna size is small, and angular resolution is high, is more suitable for use when ship carries out motor-driven in the case where close to each other.In general,
Medium-sized or above ship can equip X frequency range and S frequency range radar simultaneously, meet the application of different scenes.Spitkit is limited due to space
System then only installs X frequency range radar.
Difference of the solid-state radar in working principle with magnetron radar, makes it have apparent performance excellent compared with magnetron radar
Gesture.Solid state power amplifier is powered using DC low-voltage, reduces personnel's electric shock risk, and equipment dependability is higher；Reliability is much higher than
Magnetron, reaches 50000h, and product life cycels are at low cost；Pure low pressure emission, it is highly-safe；Out-of-band radiation is low, to other
Equipment influence is small, and Electro Magnetic Compatibility is good；The instantaneous start and stop of transmitter, do not need any preheating time；It, can using pulse compression signal
Reduce by 100 times of RF peak power or more；While improving distance resolution, operating distance is farther；Realize Coherent signal processing,
Target detection capabilities are stronger；Bandwidth of operation is wider, it can be achieved that frequency diversity inhibits sea clutter.Solid-state radar can also avoid magnetic control
It manages intrinsic booting preheating time, realizes that booting is used.And traditional magnetic control transmitter in terms of reliability and service life all
Poor, the output signal spectrum of transmitter is wider, frequency is unstable.
Due to above-mentioned advantage, realize that ship-navigation radar design is widely used using solid state power amplifier, but existing solid
There are blind range zone for state radar, cannot achieve effective detection at short distance, and its transmission power is limited, can not trigger
The beacon source of marine distal end, so that its use has some limitations.The Second Academy, China Aerospace Ke Gong group 23 is designed to be realized
Binary marine navigation radar, using the solid state transmitter of coherent system, continuous processing train of pulse is final non-maintaining, reliably
Property greatly improves.Meanwhile continuous wave detection mode is added on the basis of pulse detection mode, resolution ratio is significantly improved,
The distance between two floating materials can be distinguished more than 2.5 meters.In addition, the peak power of radar is also reduced to 1 watt from 200 watts,
Effectively reduce radiation.The radar solves pathfinder using the pulse regime combining continuous wave system of solid state power amplifier and detects closely
The problem of blind range zone, but can not equally trigger the beacon source of distal end.New radar system is needed to solve the above problems.
Summary of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of ship-navigation radar based on binary transmitter,
It is mainly used for detecting each type objects around ship carrier, such as ship, navigation mark, bridge pier, embankment, floating ice, island, iceberg, seashore
Line etc. provides visual and clear target range and bearing data to crewman, sends a warning message as needed, evade dangerous obstacles
Object prevents collision accident, guarantees marine operation safety or smoothly moors anchor.
