(application number: 201120002094.8) disclosed is a kind ofly to supervise the four unification T/R assemblies that inspection unit etc. constitutes mutually by housing, emitting module case, receiving unit case, emitting module, receiving unit, control and the width of cloth to Chinese patent " a kind of high integration four unification T/R assemblies "; This assembly has solved the interference of radiating portion strong electromagnetic radiation to reception, control section, and Electro Magnetic Compatibility is good.But also there is following weak point in prior art:
1. the T/R assembly housing belongs to seal chamber, receives " cell breath " influence bigger.Usually the technological means of seal chamber solution " cell breath " has welded seal, glueds joint sealing, embedding, the sealing of O RunddichtringO, oil sealing, package encapsulation; These technological means or sealing back maintainability are poor; The long-term outdoor rugged environment of incompatibility can not satisfy the requirement of T/R assembly housing to environmental suitability in a word comprehensively.
2. T/R assembly housing processing technology relative complex, manufacturing cost is high.T/R assembly housing structure adopts gilled radiator structure usually after hot design of Simulation, though radiating effect is better, processing technology is complicated, and production cost is high.
Summary of the invention
The objective of the invention is problems such as T/R assembly housing impermeability is bad, strong electromagnetic, heat dispersion difference in order to solve; A kind of T/R assembly with version of " bimodal " sealing strip is provided; Solved impermeability and the strong electromagnetic problem of T/R assembly in housing; Promote the adaptive faculty of radar environment, effectively guaranteed the reliability in the radar use.
The present invention for realizing the technical scheme that purpose is taked is: a kind of shell structure of phased-array radar T/R assembly: comprise the driving source module of T/R assembly housing, the sealing of aluminium box, receiver module, first shielding gasket, secondary shielding packing ring, packing washer and the case lid of aluminium box sealing; It is characterized in that: first shielding gasket is installed between the aluminium box and T/R assembly housing of driving source module of metallic aluminium box sealing, is fixed on the T/R assembly housing; The secondary shielding packing ring is installed between the aluminium box and T/R assembly housing of receiver module of metallic aluminium box sealing, is fixed on the T/R assembly housing; Packing washer is installed between T/R assembly housing and the case lid, and is fixed together.Its beneficial effect is: first shielding gasket, secondary shielding packing ring, packing washer are formed the version of " bimodal " sealing strip together, have solved impermeability and the strong electromagnetic problem of T/R assembly in housing.Promote the adaptive faculty of radar environment, effectively guaranteed the reliability in the radar use.
The shell structure of aforesaid a kind of phased-array radar T/R assembly is characterized in that: long 420 mm of said housing, wide 300mm, high 60mm.Its beneficial effect is: the volume that optimization back maximum can reduce the T/R assembly housing is about 66%.
The shell structure of aforesaid a kind of phased-array radar T/R assembly is characterized in that: it also comprises radiating groove, and radiating groove and T/R assembly housing are same metal solid.Its beneficial effect is: reach radiating effect simultaneously, effectively alleviate the weight of T/R assembly housing, reduced the production cost of T/R assembly.
The shell structure of aforesaid a kind of phased-array radar T/R assembly is characterized in that: the area of dissipation of said radiating groove: 9 * 10
5Mm
2Its beneficial effect is: the weight that can reduce housing radiating groove 6 is about 25%.
The shell structure of aforesaid a kind of phased-array radar T/R assembly is characterized in that: it also comprises ventilated membrane, and ventilated membrane is fixed on the T/R assembly housing.Its beneficial effect is: solved because of rugged surroundings change and cause " cell breath ".
