Radar for detection of concealed objects

Multi-channel continuous wave radar for detection of concealed objects configured to transmit and receive horizontally, vertically or circular polarized waveforms comprising:

• as minimum one transmitter module comprising transmitting chain including phase lock loop signal generator, and controllable power amplifier coupled to as minimum one antenna continuously covering of entire area of observation or subdivided sector and connected by digital interface to wireless transceiver module and INS/GPS module;
• multiple multi-beam receiver antenna modules comprising multiple directional antennas wherein antenna patterns overlap in one or more directions for creating monopulse subarrays continuously covering of entire area of observation or subdivided sector and comprising multiple conditioning receiving chains including voltage or current limiters, anti-aliasing circuits wherein each conditioning receiving chain coupled with separate directional antenna and software defined radio;
• each directional antenna formed by subarray of antenna elements arranged in module volume, on module surface or combined;
• all multi-beam receiver modules connected to multi-channel signal processor, wireless transceiver module and INS/GPS module by digital interface arranged as universal serial bus (USB) or microwave and/or fiber optic waveguides;
• multi-channel signal processor comprising memory, monopulse processor, objects identification means and synchronization means, wherein memory arranged for storing executable instructions and for separate processing of amplitudes, phases, frequency components shift of signals in transmitting and receiving chains, monopulse processor arranged for simultaneous multi-axis processing of all signals in receiving chains for calculating objects azimuth and range as ratio of amplitudes and/or phase shift of signals, one-iteration adapting to decrease transferring media influence to receiving chain parameters by phase shift in subarray of neighboring directional antennas with overlap antenna patterns;
• objects identification means arranged to transform three-dimensional interferogram from time domain to frequency domain, creating spectrum signatures and identification of objects, synchronization means arranged for synchronizing transmitting, receiving chains and software defined radios with multi-channel signal processor time;
• transmitter module and plurality of multi-beam receiving modules can be distributed in area, where concealed object may be positioned or by some order on carrier/satellite, vehicle or distributed between swarm or constellation of carriers/satellites to cover entire sky or area of observation.
