Abstract

The invention discloses a radar detection blind area calculation method and device. The radar detection blind area calculation method comprises the following steps: acquiring digital down-conversion radar data; supplementing N zeros to the tail of the radar data to obtain zero filling data, wherein N is the number of filter coefficients; performing pulse compression on the zero filling data by using a finite-length unit impulse response filter in a field-programmable gate array; and carrying out target solution on the data after pulse compression. According to the radar detection blind area calculation method and device, the radar performance is high, and the short-distance detection probability is high.

Description

technical field [0001] The invention belongs to the technical field of radar, and in particular relates to a method and device for calculating a radar detection blind area, a storage medium and electronic equipment. Background technique [0002] In recent years, with the improvement of radar detection performance requirements, the requirements for radar blind zone, longest detection distance and target distance accuracy are also getting higher and higher. For a radar system that integrates transceivers, radar blind spots and radar power are mutually exclusive. Reducing radar detection blind spots will inevitably lead to a decrease in detection power. In engineering applications, short codes are usually used to supplement blind spots to reduce radar blind spots and improve radar performance. The purpose of might. However, this method not only increases the difficulty in the design of signal processing, but also has a certain impact on the performance index of the radar. [...
