Problems solved by technology

However, since the distance between the radar target and each spatially separated radar may be different, the echo signals of each channel may have different signal-to-noise ratios, thereby degrading the detection performance of the square-law detector

Abstract

The invention provides a multi-radar joint detection method and device based on a Gaussian kernel. The method comprises the following steps: carrying out square law detection on a plurality of channelecho signals formed by a plurality of radars to obtain a plurality of channel echo signals after detection; setting a fixed value according to the detected echo signals of the plurality of channels;and carrying out Gaussian kernel-based signal fusion detection according to the plurality of channel echo signals after detection and the fixed value so as to determine whether a target exists or not.According to the method, in radar detection, the Gaussian kernel is used for fusing the echo of each channel, so that the fusion accuracy can be greatly improved under the condition that the signal-to-noise ratio of each channel is unknown, and the radar detection performance is improved.

Description

technical field [0001] The invention belongs to the technical field of radar detection, and in particular relates to a Gaussian kernel-based multi-radar joint detection method and a Gaussian kernel-based multi-radar joint detection device. Background technique [0002] The multi-radar system consists of a signal fusion center and multiple spatially distributed radars. In addition to receiving the echo signal of its own transmitted signal, each radar also receives the echo signal of other radar transmitted signals to form echo signals of multiple channels. , and then the signal fusion center processes the received echo signal data. Compared with a single radar, a multi-radar system has stronger reliability, survivability and anti-interference ability, and can effectively expand the detection range. [0003] At present, in multi-radar joint detection, the uniformly weighted square-law detection method is commonly used for detection. When the signal-to-noise ratio (SNR) of eac...
