Description
Technical field
The present invention relates to air defense installation field, in particular it relates to a kind of low altitude coverage radar system.
Background technology
Along with the raising of China political economy status in the world, domestic and international security protection market facing challenges is increasing.
At present, the requirement drive in domestic and international security protection market is mostly derived from two classes and threatens: traditional threat and non-traditional threaten completely.Pass
System security threat is primarily referred to as the military threat that country faces and the military factors threatening world security.Non-traditional security is also called
" new security threat ", refers to the security threat that the human society past do not runs into or seldom met；Specifically, refer in recent years
Gradually security threat prominent, that generation is outside battlefield.Terrorism, transnational crime, smuggling traffic in drugs, pirate etc. in recent years
Non-traditional threat gradually highlights, it has also become the safety problem that the world is the most thorny.Long-range strike under Information Condition
In the case of ability strengthens, requirements at the higher level are proposed in urban civil air defense sky feelings early warning.
Summary of the invention
The present invention is to solve that above-mentioned technical problem provides a kind of low altitude coverage radar system, it can realize low latitude, surpass
The good detection of low target, and capacity of resisting disturbance is strong.
The present invention solves the problems referred to above and be the technical scheme is that
A kind of low altitude coverage radar system, including display device, R-T unit and driving means, described R-T unit includes receiving
Device and discharger, described discharger includes frequency mixer, filter amplification circuit and the transmitting antenna being sequentially connected with；Described connect
Receiving apparatus includes reception antenna, low noise amplifier circuit and the immunity module being sequentially connected with, and described frequency mixer connects frequency
Rate synthesizer and local oscillator, described local oscillator and low noise amplifier circuit be both connected on coherent detection circuit, described relevant inspection
Wave circuit is connected with display device by signal processing circuit.The search radar system of the present invention its to may be installed offroad vehicle etc. low
On empty warfare equipment, it can realize low latitude, the good detection of treetop level target, and capacity of resisting disturbance is strong.
As preferably, the described supply module also including powering for display device, R-T unit and driving means, described confession
Electricity module includes power storage module and Voltage stabilizing module.
As preferably, in order to improve the reliability of reception, described reception antenna is for including multiple bay.
Further, described reception antenna includes 4 bays, and described reception antenna squarely arranges.
To sum up, the invention has the beneficial effects as follows:
The search radar system of the present invention its may be installed on the low latitude warfare equipment such as offroad vehicle, it can realize low latitude, ultralow
The good detection of null object, and capacity of resisting disturbance is strong.
