In [28] the performance of OS-CFAR in a 77GHz radar sensor for car application is examined. In the automotive radar application case multiple target situations occur almost always.

In general, the tracking procedure starts with an association process to combine the established track parameter with the radar sensor or radar network measurements. Errors in the association process will always lead to ghost targets. But the general requirement for automotive applications is to keep the false alarm probability as low as possible, which underlines the importance of the association process for radar networks. 

It has to be noted that the measurement values for range and velocity are not uncorrelated according to the LFMCW measurement described in section 8. As a consequence, the observed measurement errors ft, can also be considered as correlated random variables for a single sensor s data. For 24GHz pulse radar networks, developed also for automotive applications, a similar idea has been described by a range-to-track association scheme [12], because no velocity measurements are provided in such a radar network.

As microwave devices above 50 GHz are rarely used in civil applications, a useful design is necessary for the ACC radar. The development must concentrate on reasonable cost, high environmental robustness, and (very important for the automotive application) small size.

Components produced by shear forming are mainly parts for the automotive and aerospace industries, along with art objects, musical instm-ments, and kitchenware. Typical examples are jet engine and turbine components, dishes for radar antennas, and domestic utensils. The process is capable of forming components of diameters ranging from 3 mm to 10 m, and thicknesses of 0.4-25 mm (Brown 1998). Figure 1 shows the main features of the process and examples of obtainable geometries. 

Speaking of military fuel cell applications, we must first point out the following. Most versions of fuel cell-based power plants are of ambivalent utility they are just as good for civil as for military purposes. Thus, the stationary power plants of different sizes used for unintermptible emergency power supplies for military objects such as forts, command centers, radar stations, and the like do not differ in any way from similar power plants for civil use in hospitals, telecommunications installations, computer centers of banks, and so on. Power plants for automotive land and water-bound means of transport are equally good for civil and for military vehicles. This is true, even more directly, for power sources intended to supply portable equipment. A lower volume and weight of all equipment carried by soldiers in combat (e.g., as a means of communication, as a means of orientation, as night-vision devices) is a very important point for land forces. 

Figure 6.5 shows the Radar screen of ASD SSG with tracked, candidate and adopted standards of the European Aerospace and Defence. Considered standards are ASD external standards (e.g. adopted STEP AP214 Core data for automotive mechanical design processes ), standards for which ASD SSG monitor the development (e.g. JT), external standards for which ASD SSG participate to the development (e.g. STEP AP242) and standards ASD develops (e.g. TDP Message).
