Abstract

The invention provides a two-dimensional frequency-phase scanning small target detection system, aiming to provide a target detection system which is high in discovery rate, optimal in low-attitude detection performance, and high in anti-interference capability. The antennas of a horizontal sub-array and a vertical sub-array are connected with their respective microwave networks through their respective T/R components, the microwave networks are connected with receivers via n channels, the control information is sent to the T/R components via wave controllers through a time sequence and timing generator, frequency synthesizers are controlled by the time sequence and timing generator to generate excitation signals, the excitation signals are sent to the microwave networks via pre-amplifiers, the microwave networks radiate the beam through the T components to the antennas to the specified detection airspace and control the R components in the arrays to receive the radar echoes specified by emission, the radar echoes are sent to the receivers to signal processors for target detection after being amplified by each column of R components, the target detection data of the horizontal sub-array and the vertical sub-array are integrated, so that the high angle detection accuracy of orientation and pitching is achieved.

Description

technical field [0001] The invention relates to a special T-shaped two-dimensional frequency-phase scanning small target detection system. Background technique [0002] As the backbone radar in the short-range air defense system, the three-coordinate radar system can be divided into fixed multi-beam (stacked multi-beam and synthetic multi-beam) system, one-dimensional electronic scanning (frequency scanning, phase scanning) system and two-dimensional phase scanning (phased array) system three types. Modern so-called one-dimensional phase-scanning radars are generally referred to as three-coordinate radars, and two-dimensional phase-scanning radars are generally called phased arrays. When designing the display content of the traditional two-dimensional electronically scanned phased array radar, some use one-time information tracking data. Due to the large amount of data, the signal processing is limited, resulting in a very small A-display echo range; some use one-time Alth...
