Abstract

The invention belongs to the field of a radar sidelobe cancellation antenna and particularly relates to a method for improving the coverage effect of a P-band radar sidelobe cancellation antenna. According to the method, a first layer annular support, a first microstrip plate, a second layer annular support, a third layer annular support, a second microstrip plate, a fourth layer annular support,a fifth layer annular support, a third microstrip plate, a sixth layer annular support, a seventh layer annular support, a fourth microstrip plate, an eighth layer annular support, a one-to-four phaseweighted power division network and an antenna base, wherein the microstrip plates are eight microstrip dipole antennas integrated on the same base plate through the one-to-eight power division network. The method is advantaged in that problems of non-high coverage efficiency, over-large azimuth amplitude fluctuation and poor portability existing in a sidelobe cancellation antenna in the prior art are solved.

Description

technical field [0001] The invention belongs to the field of radar sidelobe cancellation antennas, in particular to a method for improving the coverage effect of P-band radar sidelobe cancellation antennas. Background technique [0002] At present, sidelobe cancellation antennas have been widely used in various radar and communication equipments; The main problems are the limited bandwidth, the low coverage efficiency of the sidelobe of the radar elevation plane, and the large fluctuation of the azimuth plane. The original radar sidelobe cancellation antenna system has low coverage efficiency on the pitch plane, large fluctuations in the azimuth plane (about ±1.5dB), large investment, large space occupation, inconvenient installation, and poor portability, etc. defect. Contents of the invention [0003] Aiming at the deficiencies of the background technology, the present invention provides a method for improving the coverage effect of the P-band radar sidelobe cancellati...
