2 results about "Pulse interval modulation" patented technology

The application discloses a radar signal processing method based on TOA sequence correlation degree, which comprises the following steps: parameter initialization; obtaining a radar signal pulse description word; dividing the radar signal pulse description word by using a grid method; extracting grids with a pulse number higher than a threshold value, and traversing all the extracted grids to extract the features of all the pulses contained in the grids in the TOA dimension, and the features are described by using TOA sequence feature vectors to obtain the TOA sequence feature vectors corresponding to each grid; quantifying the correlation degree between the TOA sequence feature vectors extracted by different grids to obtain corresponding correlation coefficients; performing grid merging and clustering, and outputting a radar signal clustering result. The method has high accuracy when clustering a multi-parameter agile periodic scanning radar, and is not affected by the pulse interval modulation mode of the radar. In addition, when facing a multi-parameter agile radar, the method can effectively prevent the problem that a traditional clustering algorithm is prone to produce an increased batch result.

This application discloses a flash memory controller and its data processing method. The method includes: acquiring input data; encoding the input data into a pulse sequence based on a preset pulse interval modulation strategy; wherein the width and duty cycle of the pulse sequence are within preset ranges; performing preset operations on a preset memory array based on the pulse sequence and outputting the operation results; wherein the preset operations are matrix multiplication-addition or convolution operations; and performing error correction processing on the operation results based on a preset error prediction model and outputting the target calculation result. Therefore, by encoding the input data into a pulse sequence that conforms to preset parameters and directly performing preset operations such as matrix multiplication-addition or convolution on a preset memory array, in-situ data computation is achieved, effectively reducing the frequent data transfer between storage units and computing units in traditional architectures, thereby significantly reducing energy consumption caused by data transmission.
