Problems solved by technology

Using traditional active or passive area array antennas to realize two-dimensional electronic scanning technology is complex, costly, and worth tens of millions. It can still be used in special equipment such as airports, but it has no promotion and application value in a large number of civilian fields and cannot meet the requirements. need

Abstract

The invention discloses a two-dimensional electric scanning three-coordinate radar method based on an inverted T-shaped linear array. The two-dimensional electric scanning three-coordinate radar method comprises the steps of: S1, designing a linear array sub-antenna; S2, designing an inverted T-shaped structure configuration; S3, designing and measuring an azimuth multi-beam angle; S4, and designing related azimuth and pitch frame scanning. The two-dimensional electric scanning three-coordinate radar method realizes the two-dimensional electric scanning three-coordinate function, prolongs theFFT phase coherent accumulation time by means of pulse pressure and FFT time-frequency composite processing and a large space solid angle, further improves the Doppler resolution capability and the ground clutter suppression capability, comprehensively realizes simultaneous monitoring of a space target and a ground target, thus enables a radar to integrate multiple functions of a search warning radar, a target indication radar, a tracking radar, a space monitoring radar and a ground and sea surface monitoring radar, and has the advantages of simple implementation, low purchase cost and operation cost, high measuring precision of azimuth angle, pitch angle, distance and speed, short frame scanning period, high data rate and good track quality.

Description

technical field [0001] The invention relates to the technical field of radar search and tracking, and more specifically refers to a two-dimensional electronic scanning three-coordinate radar method based on an inverted T-shaped linear array. Background technique [0002] Two-dimensional electronically scanned three-coordinate radars are divided into three types. One is the classic phased planar array radar, which realizes two-dimensional electronically scanned by changing the phase difference of the array elements in the azimuth and elevation directions, and can cover the airspace beam hopping , with three-coordinate precise measurement functions such as azimuth, pitch angle, and distance, and multi-target tracking functions. In this system, the array elements of the area array antenna rely on active TR components or ferrite phase shifters. The number of array elements is large and the cost is high. Typical examples are the US Aegis ship-borne four-sided array SPY-1 radar, a...
