First Claim
1. A historical radar data analysis method comprising:
- operating at least one radar apparatus to transmit radar pulses;
further operating said at least one radar apparatus to receive radar echoes;
additionally operating said at least one radar apparatus to generate, from the received radar echoes, radar target data including radar target tracks;
operating a radar data server to continuously receive in a real-time fashion said radar target data including said radar target tracks generated by said at least one radar apparatus, said radar data server including a SQL or structured query language database, the operating of said radar data server including operating said SQL or structured query language database to organize, insert and store the received radar target data including said radar target tracks in a real-time fashion as organized radar target data (i) so that said organized radar target data including said radar target tracks are made available for immediate access from said database as real-time target data by a radar display or processor that operates in a real-time fashion, continuously being updated by said radar data server, and (ii) so that said organized radar target data stored in said database can be queried for subsequent access as historical target data, said historical target data being taken from the group consisting of (i) said radar target tracks and (ii) threat alerts;
operating a user application on a computer to communicate, to said radar data server, a request for target data from said historical target data;
further operating said radar data server to receive said request, select and extract the requested target data from said database and send said requested target data to the requesting user application; and
further operating said user application on said computer to receive, from said radar data server, said requested target data from said historical target data in said database.

Abstract
A real-time radar surveillance system comprises at least one land-based non-coherent radar sensor apparatus adapted for detecting maneuvering targets and targets of small or low radar cross-section. The radar sensor apparatus includes a marine radar device, a digitizer connected to the marine radar device for receiving therefrom samples of radar video echo signals, and computer programmed to implement a software-configurable radar processor generating target data including detection data and track data, the computer being connectable to a computer network including a database. The processor is figured to transmit at least a portion of the target data over the network to the database, the database being accessible via the network by at least one user application that receives target data from the database, the user application providing a user interface for at least one user of the system.
