1. A method of compressing radar data in a radar system of a vehicle, the method comprising:
receiving, at the radar system, operational condition information from a mobile computer system regarding one or more operational conditions regarding the vehicle, wherein the operational condition information is obtained by the mobile computer system using at least one of data from one or more non-radar sensors of the vehicle or data received via communication with another device;
determining, from a plurality of compression modes of operation, a compression mode of operation for compressing the radar data at a particular compression level based at least in part on a likelihood of collision of the vehicle with at least one object indicated by the operational condition information, wherein the plurality of compression modes of operation are associated with at least a first compression technique having a first compression level and a second compression technique having a second compression level, the second compression technique being different from the first compression technique;
determining one or more parameters for radar data compression based at least in part on the compression mode;
performing a radar scan with the radar system to obtain the radar data;
compressing the radar data using a compression technique according to the compression mode, wherein the compression technique is performed in accordance with the one or more parameters; and
sending the compressed radar data from the radar system to the mobile computer system.
