5.6 Interference Immunity of Radar Location and Radio Navigation Systems
125
Key criterion of the system interference immunity considers contribution of its
most important criteria in ensuring of interference protection. Additional criterion of
interference immunity, measured in decibels, serves for revealing and contribution
registration of special interference protection units and algorithms.
5.7 Specifications and Performance of Radar Location
and Radio Navigation Systems
Technical characteristics of radars and RNS, providing assigned tactical characteristics, are diverse enough. The main among them are:
• frequency band of emitted oscillations and carrier frequency;
• pulses duration and its repetition frequency;
• signal shape and modulation law;
• shape and width of directional pattern;
• radiating power (average, pulsed, peak);
• sensitivity (response) of receiving device;
• pass bandwidth;
• noise ratio;
• system mass and dimensions.
Operational characteristics of radars and RNS include the system reliability
criteria (single and complex), maintenance and repair burden (labor-intensive
characteristic), etc.
Operational characteristics of radars and RNS are specified at the stage of systems.
These characteristics should above all reflect requirements to a new developed or
upgrading system from the position of ensuring assigned fit-for-purpose requirements, ease in technical maintenance (serviceability), increase of reliability and
effectiveness of maintenance.
